If a RLC parallel circuit contains more capacitive VARs than inductive VARs, the circuit has a _____ power factor.
A) lagging
B) leading
Power Factor
The ratio of the true power transmitted to a load to the apparent power in the circuit, indicating efficiency in electrical systems.
RLC Parallel Circuit
An electrical circuit consisting of a resistor (R), inductor (L), and capacitor (C) connected in parallel, affecting the circuit's impedance and frequency response.
Capacitive VARs
Reactive power generated or absorbed by capacitive elements in an AC circuit, contributing to the total power but not to work done.
- Understand the impact of VARs (volt-ampere reactive) on power factor in RLC circuits.

Final Answer :
B
Explanation :
In an RLC parallel circuit, if there are more capacitive VARs than inductive VARs, the circuit exhibits a leading power factor. This is because capacitors provide leading reactive power, counteracting the lagging effect of inductors.
