Determine the resonance frequency ub of the circuit. Number rad s What is the maximum current when the circuit is at resonance, if the amplitude of the (ac) voltage is 36.0 V? 0.055 There is additional feedback View this feedback bar again to hide the additional feedback.

Explanation / Answer

a) for resonance , XL= Xc

Hence resonance frequency can be given as:

f = 1/(2LC)

L = 85×10-3 H , C = 5.25×10-6 F

By putting value we get f = 238.36 Hz

Now convert Hz into rad/s

f = 2×238.36 = 1496.9 rad/s

b) at resonance , current can be given as :

I = V/R = 36/651 = 0.055 A
