Resistor
2.
Briefly describe 4 factors that affect the resistance of a material.
3.
Draw a circuit diagram showing how an ohmmeter is connected to the circuit (consisting
of 1 cell, 1 light bulb, and connectors) to measure the resistance across the light bulb.
Electrical resistance is the characteristic of a material that slows electron
flow.
