Correct Answer : Option (D) : the line current and increases p.f.
Explanation : Capacitor is used to improve (increase) p.f. Therefore, line current is decreased for the same active power.
Correct Answer : all voltages and current
Explanation : KCL and KVL are valid for voltages and currents of all wave shapes during transient as well as steady state conductions.
Correct Answer : 22 Ω
Explaination :
Correct Answer : 360°
Explaination : Sum of phasors is maximum if they are in phase and 360° = 0.
