Capacitors - Technical MCQs

Q1:

What is the angle theta value for a 5.6 F capacitor and a 50-ohm resistor in series with a 1.1 kHz, 5 Vac source?

A 27.3 degrees

B 62.7 degrees

C –27.3 degrees

D –62.7 degrees

ANS:C - –27.3 degrees

Don't divide (XC/R) and calculate phase angle.

Calculate directly using (θ) = tan-1 (-XC / R).
You will get (θ) = -27.32˚.
