A resistor R and an inductor L are connected in series to a 24 V, 50 Hz supply. A current of 1 A flows through the circuit. If the current differs in phase from the applied voltage by 60°, the value of impedance in the circuit is |
21 Ω 12 Ω 17 Ω 6 Ω |
21 Ω |
The correct answer is Option (1) → 21 Ω |
