NEET 2021 Physics LCR Circuit MCQ Question
Type: MCQ-numerical-Medium-Class 12
An inductor of inductance L, a capacitor of capacitance C and a resistor of resistance 'R' are connected in series to an ac source of potential difference 'V' volts as shown in figure. Potential difference across L, C and R is 40 V, 10 V and 40 V, respectively. The amplitude of current flowing through LCR series circuit is 10√2 Å. The impedance of the circuit is :
A
4√2 Ω
B
5/√2 Ω
C
4 Ω
D
5 Ω
Correct Answer
Option D
Detailed Explanation
The impedance Z in an LCR circuit is calculated using Z = V/I. Given V = 40 V and I = 10√2 Å, Z = 4√2 Ω.
