PHYSICS ELECTRICITY QUESTIONS
AND ANSWERS WITH SOLUTIONS 2024
Electric Fields - ANSWER The direction of an electric field is the direction a positive charge would move in
if free to do so. Fields go away from positive charges and towards negative charges.
Current - ANSWER a flow of electricity through a circuit.
Measured in Ampheres (A).
Voltage - ANSWER Is a measured of the amount of energy available to push charges around in a circuit.
Voltage is measured in Volts (V).
Conductors - ANSWER Materials that allow electric charges to flow through them easily.
Insulators - ANSWER Materials that prevent electric charges from flowing through them easily.
Ohm's Law - ANSWER V=IR
Where:
V=voltage
I=current
R=resistance
Resistance - ANSWER Resistance is a measure of a components ability which slows or reduces the
current.
Power - ANSWER Electric Power is the rate at which electrical energy is transferred by an electric circuit.
Measured in Watts (W).
Calculated By: P=IV
P=power in watts
I=current in amps
