Title: Ohm’s Law

Abstract:

Experiment #5 will familiarize ourselves      with   Ohm’s           Law   to prove         how   current and    voltage          are     linearly proportional to a dc circuit. Also that the proportionality constant is the same as resistance.

Introduction:

In this lab         we will need to know what Ohm’s Law is which is V=IR. We can use  this            equation  to also find the current (I) and        the     resistance       ( R).  To         prove  Ohm’s                     Law     we need           to create         a  circuit         and measure both the voltage and the current as it changes to see if it’s linear.

Simulation:

The procedure can be found on Chapter 5 page 23-24 in Experiments in Electric Circuits 9th Edition

Experimental:

Voltage (V): 1V-9V

Current (I): ?mA

Resistance (R): 1kΩ, 2kΩ 

Results:

1 kΩ (100mA)

Discussion:

1) B

2) B

3) A

4) A 

5) At these points they show the difference in conductance on how one is doubled the other being parallel lines.

Conclusion:

In the end we were able to prove Ohm’s Law by setting up circuits to measure the

current and the voltage of theses circuits. Because of this we now have a better understanding of Ohm’s Law.
