A Series LRC Circuit Consists of an Ac Voltage Source

question 21

Short Answer

A series LRC circuit consists of an ac voltage source of amplitude 75.0 V and variable frequency,a 12.5-µF capacitor,a 5.00-mH inductor,and a 35.0-Ω resistor.
(a)To what angular frequency should the ac source be set so that the current amplitude has its largest value?
(b)Under the conditions of part (a),what is the maximum current amplitude?
(c)Suppose that the voltage source is set to twice the angular frequency needed in part (a).What will be the current amplitude in this case?
