Question

A 50 Ω resistor, 100 mH inductor and 60 μ F capacitor are connected in series to an AC
generator. The generator produces 60 V r m s at 30 Hz. What is the maximum current in
the circuit at 30 Hz?

Answer 1

Given data:

Resistance(R) = 50 Ω

Inductance (H)= 100 mH

capacitor (C) = 60 μ F

V_rms = 60 V

Frequency (f) = 30 Hz

Now; Capacitor impedence in ohms =

and Impedence due to inductor in ohms

Now to calculate I_max ;

maximum current in the circuit at 30 Hz = 0.700 Ampere
