Purpose:

The purpose of this experiment is to study the basics of a direct current circuit. There are several parts to this experiment, where resistors are set up as parallel, series or both. We measure the potential difference and current measured by voltmeter and ammeter respectively. Also, we set up a Wheatson Bridge to measure the unknown resistor.

Equipment:

Voltmeter PCC 000218
Galvanometer PCC 000180
Resistance Boxes PCC 000128, PCC 001363, and PCC 001373
Multimeter PCC 000115 and PCC 001322
Power Supply PCC 000180
Ammeter PCC 001613
Linear Resistor With Sliding Scale PCC 000697
Wires

Data and Analysis:

Discussion:

The percentage error that we get for all for parts of the experiment ranges from 0.611% to 6.40%. These possible sources of error were machine malfunctions and human error. The machine could not have been hooked up correctly or the equipment could not have been up to date. Human error could include writing the values down wrong, misusing the materials, or reading the scale carelessly. To improve the experiment, we can use all digital meters instead of scales and replace the equipment that we use with better and newer ones. For human error, we should pay more attention and carefully set up the equipment.

Conclusion:

The purpose of this experiment is to set up a circuit in such a way that we can get least error. This experiment gives us the chance to apply the theories that we get from our textbooks and lectures about DC Circuits. The percentage errors were reasonable amounts. The percentage errors we got for all 5 parts of the experiments, part I, part II(a), part II(b), part III, and part IV are: 5.20%, 0.611%, 6.40%, 5.11%, and

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…

Lee 1 Kwan Woo Lee Lab Report#1 Measurements in resistive networks and circuit laws laboratory Abstract: The purpose of this lab is to verify the Ohm's Law, Kirchhoff's Voltage and Current Laws. As well as the introduction to the voltage division. The Ohm's Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points (V = IR). The Kirchhoff's Voltage Law states that the directed sum of the electrical voltage…

Experiment 5: RC Circuits Abstract The purpose of this lab is to learn and understand RC Circuits. An RC circuit is composed of at least one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do not want the plates to be touching, because then we would only have a conductor. The insulator between the plates is also known as the dialectic, which affect how the capacitor will store…
