Q1. Suppose an AC circuit has a resistance of 15 Ω and an inductive reactance of 25 Ω. What is the impedance of the circuit?
Answer: 35 Ω
Explanation: The correct answer is 35 Ω because impedance (Z) is the vector sum of resistance (R) and reactance (X). Z = √(R^2 + X^2) for an inductive circuit. Option A is the reactance, option B is the result of a calculation error, and option D is the resistance.
