Question : 32

Total: 40

Solution:

Concept:

According to Ohm's law, the potential difference across a resistor is the product of the current flowing through it and its resistance.

Explanation:

Given: Current

I = 3\,\text{A}

and Resistance

R = 4\,\Omega

The formula is

V = I \times R

Substitute the values:

V = 3 \times 4 = 12\,\text{V}

Therefore, the potential difference across the resistor is

12\,\text{V}

Answer:

12.00\,\text{V}
