# Basic Electrical Engineering MCQ

Q:

The quadrature component is also known as?

 A) Active component B) Reactive component C) Either active or reactive component D) Neither active nor reactive component

Explanation: The quadrature component is also known as the reactive component because the reactive component forms a quadrature with the voltage.

Q:

The phase difference between the active component of an impedance parallel circuit and the voltage in the network is __________

 A) 0 B) 90 C) 180 D) 360

Explanation: The active component in an impedance parallel network will always be in phase with the voltage in the circuit. Hence the phase difference is 0.

Q:

The active component in an impedance parallel circuit will __________ the voltage.

 A) Leads B) Lags C) Be in phase with D) Either leads or lags

Explanation: The active component in an impedance parallel network will always be in phase with the voltage in the circuit.

103
Q:

The reactive component in an impedance parallel circuit leads the voltage when the current _________ the voltage.

 A) Leads B) Lags C) Either leads or lags D) Cannot be determined

Explanation: The reactive component in an impedance parallel circuit leads the voltage when the current leads the voltage.
