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
- A 24 Ω
- B 12 Ω
- C 17 Ω
- D 6 Ω
Answer & Solution
Correct Answer
(A) 24 Ω
Step-by-step Solution
Detailed explanation
\(Z = \frac{V}{I}\) \(Z = \frac{24 \, \text{V}}{1 \, \text{A}}\) \(Z = 24 \, \Omega\)
