EXPLANATION
Question: The SI unit of frequency is:
- a) Ohm
- b) Coulomb
- c) Hertz
- d) Ampere
ANSWER: c) Hertz
EXPLANATION:
The SI unit of frequency is hertz (Hz). So the answer is (c).
Frequency is the number of cycles per second of a wave. It is measured in hertz, which is defined as one cycle per second.
Ohm is the SI unit of electric resistance. Coulomb is the SI unit of electric charge. Ampere is the SI unit of electric current.
