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