Apparatus
1. Joykey
2. 2 dry cells (1.5 V each) connected in series
3. Ammeter (0 – 2A)
4. Potentiometer
5. Key/switch
6. Standard resistor, R of resistance, 2 Ω
7. Connecting wires
Objective
To determine the resistance of a standard resistor using Ohm’s law
Note: At 14:50 , there was a slight error in the formula for the y-intercept. It should be c = -R0A/p.
