AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

Q1. [1] straightforward initial-understanding
In an electric circuit, the potential difference across a resistor is 12 V and the current through it is 3 A. What is the resistance of the resistor?

Model Answer

Using Ohm's law: $R = \dfrac{V}{I} = \dfrac{12 \text{ V}}{3 \text{ A}} = 4\ \Omega$

The resistance of the resistor is 4 Ω.

Source: Chapter 11, Ohm's Law

Explanation

This is a direct application of Ohm's law: $V = IR$, so $R = V/I$. Always write the formula, substitute values with units, and state the final answer with the correct SI unit (Ω). Examiners award the mark for the correct substitution and answer.
