Question

A circuit contains two unequal resistances in parallel.
Options
A currents same in both resistors
B larger current flows in larger resistor
C potential difference across each is same
Correct Answer
D smaller resistance has smaller conductance
Correct Answer

Option C is the correct answer.

Detailed Explanation

In a parallel circuit, one of the fundamental properties is that the potential difference (voltage) across all parallel branches or components is the same. The current, however, divides, with more current flowing through the path of least resistance. Conductance is the reciprocal of resistance, so a smaller resistance implies a larger conductance, not smaller.

Hint

Recall the fundamental laws governing voltage and current distribution in parallel circuits.
