Question

What is the phase difference between voltage and current at half power frequency

Answer 1

Explanation:

The phase difference between voltage and current in series Icr circuit at half power frequency,

is the Voltage across the resistance will be in phase with that current, and

the Voltage across the capacitance must

lag the current by 90 degrees,

while the Voltage across the inductance must lead the current by 90 degrees.

This makes the inductance and capacitance Voltages 180 degrees out of phase.
