Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When two unequal resistors are connected in parallel across a voltage source, the larger current flows through the resistor having the smaller resistance. Reason (R): The equivalent resistance of a parallel combination of resistors is always less than the smallest individual resistance present in t

Options

  1. ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).
  3. CAssertion (A) is true but Reason (R) is false.
  4. DAssertion (A) is false but Reason (R) is true.

Correct answer

B. Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

Step-by-step solution

In a parallel circuit, the potential difference ( V ) across each resistor is the same. According to Ohm's law, I = V R . Since V is constant, I 1 R . Therefore, a smaller resistance will draw a larger current. Thus, Assertion (A) is true. The equivalent resistance ( R_ eq ) for resistors in parallel is given by 1 R_ eq = 1 R₁ + 1 R₂ + This mathematical relationship ensures that R_ eq is strictly less than the smallest individual resistance in the parallel combination. Thus, Reason (R) is also true. However, the fa
