Question

I ONLY NEED PART E . All other parts were answered correctly. Answers are below if needed. thanks

An RLC series circuit has a 2.70 resistor, a 160 µH inductor, and an 82.0 µF capacitor.

a) Find the circuit's impedance (in ) at 120 Hz. = 16.286

b) Find the circuit's impedance (in ) at 5.00 kHz. = 5.36

c) If the voltage source has

Vrms = 5.60 V,

what is Irms (in A) at each frequency?

Irms, 120 Hz= A = .344

Irms, 5.00 kHz= A = 1.045

d) What is the resonant frequency (in kHz) of the circuit? = 1.390

e) What is Irms (in A) at resonance?

e)Given,

Vrms = 5.6 V ; R = 2.45 Ohm

At resonance, impedence in the circuit is equal to resistance since Xl = Xc, so

Z = R = 2.45 Ohm

Irms will be given by

Irms = Vrms/Z = Vrms/R

Irms = 5.6/2.45 = 2.074 A

Hence, at resonant frequency, Irms = 2.074 Amperes.
