If a RLC parallel circuit contains more inductive VARs than capacitive VARs, the circuit has a _____ power factor.
A) lagging
B) leading
Power Factor
A measure of how effectively electrical power is converted into useful work output, representing the ratio of the real power flowing to the load to the apparent power in the circuit.
RLC Parallel Circuit
An electrical circuit consisting of resistors (R), inductors (L), and capacitors (C) connected in parallel, affecting the impedance and phase of the circuit.
Inductive VARs
Volt-Amps Reactive attributed to inductance in a circuit, representing power that oscillates between the source and an inductive load but does not perform work.

Final Answer :
A
Explanation :
In an RLC parallel circuit, if there are more inductive VARs (volt-ampere reactive) than capacitive VARs, the circuit exhibits a lagging power factor. This is because inductors store energy in a magnetic field, which tends to delay the voltage phase behind the current, leading to a lagging power factor.
