Resistance Lab

The purpose of this lab was to determine what the resisatnce was, of a resistor we know nothing about.

DC Power Supply

First we created a circuit with the DC power supply, resistor and the galvonometer. Then sent different amounts of vvoltage through the circuit and read the corresponding current.

Data Analysis:

Line of best fit: y=100000x+.5

Slope=Resistance= 100000W

Because Ohms law is R=V/I, I plotted these units accordingly and it made the slope become the resisqatance, which is 1000000W


In conclusion we used our data that we recieved from our lab to make a graph plotting voltage and amps.  The resulting slope was then used to calculate what the resistance of our resistor was, which was determined to be about 100000W
