Series-Parallel Connection is also known as the combined resistive circuits. This is the combination of series circuit and parallel circuit. Series circuit can be described as a circuit with only one path for charges to move along. This was also the common circuit connection in most rural areas. On the other hand, Parallel circuit can be described as circuit with multiple paths intended for charges to flow freely. This type of circuit connection was used in most urban areas around the country. In addition, series circuit components are connected end-to-end in a line to form a single path for electrons to flow while parallel circuit components are connected between the same set of electrically common points. But nowadays, Series-Parallel Connection is the most commonly used type of circuit connection in residential areas. This type of circuit connection is more advantageous because if one component of circuit is damaged then rest of the component of the circuit will perform their work without any disturbance. This can prevent fires if ever short circuits will occur. If ever short circuit will happen, only the series connection will breakdown or be affected and the parallel connection will still work.

Equipment:
Procedure: In a circuit in which the components are soldered to a circuit board, direct measurement of current can be a nuisance. Doing so requires desoldering a connection, measuring the current in the circuit gap, and re-soldering the connection. If the circuit contains a sufficient number of resistors, it may be possible to use a voltmeter and some simple calculations using Ohm’s law to determine circuit currents. In this latter method, no desoldering is required. We demonstrate this...

...Experiment: Series and Parallel Circuits
Date Given: January 28, 2013
AIM: To investigate the circuits to tell whether the resistors are in parallel or in series also to determine the internal resistance of a 1.5V cell.
THEORY:
In this experiment it was expected of the experimenter to have a basic knowledge of circuits in both aspects theoretically and practically. A basic circuit comprises of a cell or power supply (some electric driving force) a load (some component that will use current) and connecting wires (these should be good conductors of electricity), as seen below.
Requirements of a circuit to function are it should be a closed circuit (a closed conducting path from negative to positive) also there has to be some potential difference as this causes the electrons to flow along the metal. This lab specifically investigates series circuits, parallel circuits and cells.
A series circuit has the same current flowing through all resistors adjacent to each other (in series), I=I1=I2…et cetera. The total potential difference (V) is equal to the sum of its individual potential differences, V=V1+V2. The individual potential differences are directly proportional to individual resistances, meaning each resistor in series has a corresponding voltage. The total resistance is equal to the sum of all resistances. A...

...Title: Resistors in Series and Parallel
Date: 17/7/05
Aim:
The aim of this experiment is to compare the predicted and actual resistance in a circuit of resistor combinations in series and in parallel.
Background:
A resistor is an electrical component/device that has electrical resistance. Resistors can be used in electric circuits for protection of components, voltage division or current control. In an ideal resistor the resistance remains constant regardless of the applied voltage or current, or the rate of change in the current (Resistor, 2005, Wikipedia).
Electrical resistance is a measure of the ability of an object to oppose the passage of an electric current. The electrical resistance of an electrical component can be found by using Ohm's law. Ohm's law states that the potential difference (voltage) between the ends of a conductor (e.g. a resistor) and the current flowing through the conductor are proportional at a given temperature (Storen & Martine, 2000, p221-226). This law can be written as: R=V .
I
The SI unit used for electrical resistance is an ohm. An electrical device that has an electrical resistance of 1 ohm will cause a current of 1 amp to flow through it if a voltage of 1V is passed through it.
From previous scientific research it has been determined that the general law for resistors in series is: Rseries = R1 + R2 + R3+Rn
It has also been determined that the general law for...

Abstract
The experiment is about the elements of series and parallel circuits. The laws on series and parallel resistors, as well as the color code for resistors were observed to calculate the total resistance. The proper connection for ammeter and voltmeter was also conducted and the readings for the voltage and current were obtained.
1. Introduction
The objectives of the experiment are to determine the resistance of a resistor based on its color code and to verify the laws on series and parallel resistors, as well as the cells. Some practical applications of these types of circuits are observable in our daily lives. An example of series circuit is the Christmas lights. If any one of the bulbs is missing or burned out, no current will flow and none of the lights will go on. On the other hand, an example of parallel circuits is the wiring system in our houses. If one of the lights burns out, current can still flow through the rest of the lights and appliances.

...solve problems in series and parallelconnection and the resistance of a material. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R). It can be written in three ways:
V = I × R or I =V/R or R = V/I
The resistance (R) of a material depends on
Its length,
cross-sectional area,
The resistivity, and
Resistance also depends on temperature, usually increasing as the temperature increases. For reasonably small changes in temperature, the change in resistivity, and therefore the change in resistance, is proportional to the temperature change.
Circuits consisting of just one battery and one load resistance are very simple to examine, but they are not usually found in practical applications. We find circuits when two or more constituents are connected together.
We have two basic ways of connecting circuit components:
Seriesparallel
1. Series Circuit – is an electric circuit having its parts connected serially (without branching). It has only one path for the charges to move along and the charges must move in “Series” which means first going to one resistor then the next. Here if one of the circuits is broken down, then no charge will move through the circuit because there is only one path. Which is if one bulb burned out the whole lights will go off. The lamps on a Christmas tree are connected in...

...Voltage and Current in Series and Parallel Circuits
Purpose:
The purpose of this lab was to investigate and prove Kirchhoff’s voltage and current laws, through the use of parallel and series circuits. In a parallel circuit, the voltages at different loads remain constant with themselves and the battery, where the current at different loads add up to equal the total current of the battery. Aseries circuit proves the opposite; current remains constant, and the voltages being used at different loads add up to total voltage of the battery.
Procedure:
1. Two loads were attached together by a copper wire and to two batteries to create a series circuit, as seen in figure 1.
2. The multimeter was attached to the two batteries with the black wire to the negative end of the battery, and the red wire to the positive end. This device was used to measure voltage and current in the series circuit.
3. Steps 1-2 were repeated using 3 loads.
4. The 2 loads previously used were rearranged to form a parallel circuit, as seen in figure 2.
5. The multitmeter was used to measure voltage and current in the parallel circuit.
6. Steps 4-5 were repeated using 3 loads to form a parallel circuit.
Analysis:
Kirchhoff’s laws suggest that in a series circuit, the voltages...

...3. Series and parallel circuits serve different purposes in households
1. Identify the difference between series and parallel circuits
Series is when the components line up after one another, thus there is only 1 path. In parallel there are multiple paths.
Advantages of using parallel circuitry over series circuitry in household wiring include:
* You can have some devices on and others off at the same time.
* If one device fails the others still work.
* All devices receive the highest possible voltage.
2. Compare parallel and series circuits in terms of voltage across components and current through them
In a series circuit voltage is divided evenly throughout the components, with current being the same max current throughout all the components. In a parallel circuit it is opposite, voltage is the same max voltage throughout the components, with current being divided evenly throughout the components.
In the series circuit each light will be half the brightness than if there was only one. However in the parallel circuit the lights have the same brightness no matter how many are added.
3. Identify uses of ammeters and voltmeters
Ammeters are used to measure current. Voltmeters are used to measure voltage. To measure the voltage of a component the...
