A 200 Hz AC generator produces a voltage of 200 V. If the current through a 5 Ω resistor is 2 A, what is the impedance of the circuit?
Q1. A 200 Hz AC generator produces a voltage of 200 V. If the current through a 5 Ω resistor is 2 A, what is the impedance of the circuit?
Answer: 20 Ω
Explanation: The correct answer is 20 Ω because impedance (Z) is the vector sum of resistance (R) and reactance (X). Z = √(R^2 + X^2). Option A is the resistance, option B is the reactance, and option D is the result of a calculation error.
