Question

At upper half power frequency, the expression for power (P2) is?

(a) I^2maxR

(b) (I^2maxR)/2

(c) (I^2maxR)/4

(d) (I^2maxR)/8

I have been asked this question in unit test.

I need to ask this question from Bandwidth of an RLC Circuit topic in division Resonance & Magnetically Coupled Circuit of Network Theory

Answer 1

The correct answer is (b) (I^2maxR)/2

The explanation is: At upper half power frequency, the expression for power (P2) is P2 =  (I^2maxR)/2. The response curve is also called the selectivity curve of the circuit.
