Question 3 Assertion (A): Two resistance having value R each. Their equivalent resistance is 𝑅/2. Reason (R): Given Resistances are connected in parallel. When two resistors with resistances R each are connected in parallel, let their equivalent resistance be R’.
Then,
1/𝑅′=1/𝑅+1/𝑅
1/𝑅′=((𝑅 + 𝑅))/((𝑅 × 𝑅))
R’ = 2𝑅/𝑅^2
Therefore, R’ = 2 / R
Thus,
Assertion is true.
Reasoning is true.
So, the correct answer is (a).
