EXPLANATION
Question: Which unit is used to measure electric resistance in the SI system?
- a) Ampere
- b) Volt
- c) Coulomb
- d) Ohm
ANSWER: d) Ohm
EXPLANATION:
The SI unit of electric resistance is ohm, abbreviated as Ω. So the answer is (d).
Electric resistance is the opposition to the flow of electric current. It is measured in ohms, which is defined as the voltage across a conductor divided by the current flowing through it.
Ampere is the SI unit of electric current. Volt is the SI unit of electric potential difference. Coulomb is the SI unit of electric charge.
