An R-C series circuit has a power factor of 76%. By how many degrees are the voltage and current out of phase with each other?

Question

An R-C series circuit has a power factor of 76%. by how many degrees are the voltage and current out of phase with each other?

Answer 1

The power factor (in decimal form) is just the cosine of the phase angle φ.

 

φ = cos^-1(0.76) ≅ 40.5º
