1. What is the unit used to measure electrical current?
A. Volt
B. Ohm
C. Ampere
D. Watt
Rationale: Current represents the flow of electrons in a
conductor and is measured in amperes.
Correct Answer: C. Ampere
2. What does the term “voltage” represent?
A. Flow of electrons
B. Electrical pressure that pushes current
C. Resistance to current
D. Heat generated in a circuit
Rationale: Voltage is the potential difference that drives
electric current through a conductor.
Correct Answer: B. Electrical pressure that pushes current
,3. What is the unit of electrical resistance?
A. Ampere
B. Volt
C. Ohm
D. Joule
