Question

Rate of flow of electric charge through a conductor is called _________.

• A. resistance
• B. charge
• C. current
• D. potential

Answer 1

The correct option is C

current

Explanation of correct option:

1. Current is defined as the rate of flow of charge through a conductor.
2. SI unit of the current is ampere (A).

Explanation of incorrect option:

Option (a): resistance

1. Resistance is the property of the conductor which resists the flow of current.
2. Resistance is measured in ohm.

Option (b): charge

1. Flow of charge constitutes current.
2. SI unit of charge is coulomb (C).

Option (d): potential

1. Potential is defined as the amount of work done to move unit positive charge from reference point to specific point.
2. SI unit is volt (V).

Hence, option (c) is correct.
