JEE Main 2023 (30 Jan Shift 2)

Question

In the given circuit, rms value of current Irms through the resistor R is :

Choose an option

Show full solutionCorrect option: A
Correct answer
A2 A

Step-by-step explanation

Impedance of the given LCR circuit will be, Z=R2+XL-XC2⇒Z=1002+200-1002

=1002Ω

Therefore, RMS current can be written as,

Irms=VrmsZ=20021002

=2 A
