Question

16) An alternating emf having a maximum value of 100 V and angular frequency of 120n s-1 is connected in series with a resistance of 1 Q, a self inductance of 3x 10-3 H, and a capacitor of 2x 10-3 F. The amplitude and phase of the current are: a) 98.21 A, 10.9° b) 76A, 10° c)86.33A, 15.1° d) lO0A, 11° e)none

Answer 1

given :

angular frequency = w = 120 rad/s

peak voltage = V = 100 V

R = 1 ohm

L = 0.003 H

C = 0.002 F

capacitive reactance =

inductive reactance =

Inpedance = Z =

Peak current or current amplitude = [answer]

phase difference between current and voltage = [answer]

none of the options matches.

so, correct option is (e).
