Question

What is the rate of flow of electric charges called?

• A. Electric Potential
• B. Electric Conductance
• C. Electric Current
• D. None Of These

Answer 1

The correct option is C

Electric Current

The explanation of the correct option:

Option C:

1. Current is the rate at which electric charges flow.
2. Electric current is denoted by “I”.
3. The unit of current is $\mathrm{Ampere}$.

Mathematically, electric current can be represented as:

$\mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}$

Here,

I is the current, V is the voltage, R is the resistance.

The explanation for the incorrect options:

Option A:

The amount of effort requires to move a unit charge from a reference point to a specific point in the presence of an electric field is referred to as electric potential.

Option B:

Electric conductance measures the ease with which electricity flows through electrical components for a given voltage difference.

Hence, option (C) is correct.
