The Total solution for NCERT class 6-12
A 44 mH inductor is connected to220 V, 50 Hz ac supply. Determine the rms value of the current in the circuit.
Inductance of inductor, L =44 mH = 44 × 10−3 H
Supply voltage, V =220 V
Frequency, ν =50 Hz
Angular frequency, ω=
Inductive reactance, XL = ω L
Rms value of current is given as:
Hence, the rms value of currentin the circuit is 15.92 A.
