Question

Denve an expression for average power of an a. c circuit containing L C R.​

Answer 1

Answer:

Alternating Current. Derive an expression for the average power consumed in a series LCR circuit connected to a.c., source in which phase difference between the voltage and the current in the circuit is ϕ. Figure shows a series LCR circuit connected to a variable frequency 230 V source. L = 5.0 H, C = 80 μF, R = 40 Ω.
