### voltage and current in series and parallel circuit

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. A series circuit proves the opposite; current remains constant, and the voltages being used at different...

### Circuit Lab Report

Ohm’s Law is V = I * R or in some cases I = V / R. The next two laws were established by a German physicist by the name of Gustav Kirchhoff. Kirchhoff’s first law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit, the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the total current leaving the junction. These laws...

### Series and parallel circuit problem solving

﻿Introduction My research is based on how Ohm’s law is derived and how it is used to solve problems in series and parallel connection 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...

of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact, burn fingers, create other damage.
