Resistance Practical

1

Equipment Setup

1. Set up a circuit as shown

2

Measuring Resistance

1. Tape a wire to a meter ruler
2. Connect the meter ruler to the circuit with crocodile wires
3. Record the distance between the two crocodile clips
4. Turn on the circuit
5. Record the voltage across the wire by using the voltmeter
6. Record the current in the circuit by using the ameter
7. Calculate the resistance using the equation: R=V/I

Different Resistances

1. Turn off the circuit
2. Move the crocodile clips further apart
3. Record the distance between the two crocodile clips
4. Turn on the circuit
5. Record the voltage, current, and calculate the resistance
