Question

A 40.0-uF capacitor is connected to a 50.0-ohm resistor and a generator whose rms output is 30.0 V at 60.0 Hz.

Find...

A) the rms current circuit

B) the rms voltage drop across the resistor

C) the rms voltage drop across the capacitor

D) and the phase angle for the circuit

Please Explain how to get these answers, Thankyou

Answer 1

Given:

C=40uF

R=50ohm

V=30Volt

f=60Hz

1) To find rms current

I rms = Ip/?2

But, Ip= V/R

          = 30/50

        Ip= 0.6 Amp

I rms = 0.6/?2

        = 0.4243

2) rms Voltage drop= Irms * R

                          = 0.4243 * 50

                              = 21.2134

4) phase angle= T * f * 360

                      = 0.0167 * 60 * 360

                       = 360
