This set of Basic Electrical Engineering Multiple Choice Questions & Answers (MCQs) focuses on “The Current in a Series RLC Circuit”.

1. In a series RLC circuit, the phase difference between the current in the capacitor and the current in the resistor is?

a) 0 degrees

b) 90 degrees

c) 180 degrees

d) 360 degrees

View Answer

Explanation: In a series RLC circuit, the phase difference between the current in the capacitor and the current in the resistor is 0 degrees because the same current flows in the capacitor as well as the resistor.

2. In a series RLC circuit, the phase difference between the current in the inductor and the current in the resistor is?

a) 0 degrees

b) 90 degrees

c) 180 degrees

d) 360 degrees

View Answer

Explanation: In a series RLC circuit, the phase difference between the current in the inductor and the current in the resistor is 0 degrees because the same current flows in the inductor as well as the resistor.

3. In a series RLC circuit, the phase difference between the current in the capacitor and the current in the inductor is?

a) 0 degrees

b) 90 degrees

c) 180 degrees

d) 360 degrees

View Answer

Explanation: In a series RLC circuit, the phase difference between the current in the inductor and the current in the capacitor is 0 degrees because the same current flows in the inductor as well as the capacitor.

4. In a series RLC circuit, the phase difference between the current in the circuit and the voltage across the resistor is?

a) 0 degrees

b) 90 degrees

c) 180 degrees

d) 360 degrees

View Answer

Explanation: In a series RLC circuit, the phase difference between the voltage across the resistor and the current in the circuit is 0 degrees because they are in phase.
