Question
Chapter 32, Problem 58EAP
To determine
The power factor of the series RLC circuit, cosϕ = R/Z
Introduction:
The series RLC circuit is built such that the resistor in series with the reactive elements, capacitor and inductance and connected to the source emf of ɛ.
The resistor = R
The inductance = L
The capacitance = C
The source emf =
The current supplied by the source = I
The power factor is defined as the cosine of phase angle between voltage and current.
