Question 3 Assertion (A): Two resistance having value R each. Their equivalent resistance is ๐ /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 Rโ. Then, 1/๐ โฒ=1/๐ +1/๐ 1/๐ โฒ=((๐ + ๐ ))/((๐ ร ๐ )) Rโ = 2๐ /๐ ^2 Therefore, Rโ = 2 / R Thus, Assertion is true. Reasoning is true. So, the correct answer is (a).
