A 130μF130μF capacitor is connected to a source that operates at 90Hz90Hz with a peak potential difference of 8V8V. Find:

(1 point) A 130 uF capacitor is connected to a source that operates at 90 Hz with a peak potential difference of 8 V. Find: a) the peak current: 0.588 A b) the current when the potential difference has its peak value: 0 A c) the current when the potential difference has one-half the (positive) peak value (there are two answers, list them in increasing order): -0.509 A 0.509 A d) the instantaneous power delivered to the capacitor at 4 ms. W

Answer 1

I Giren, (= 130 MP f - 90 H7 V = 8v a) Peak current - Jp = e 2 1/wc (ox 10 6 x 20 x 20 ) 0.588 A b) 1 - 0 c ) I - (since PD is maximum peak velice) WC man es fut) 0.588 Coswt) as cut = 300 & 150° I 10 & ID are 0.509 A & -10.509 A d) Inst power. I (1) WC v mes Cos (rift) 0.531 tos ( 97 x qox 4X10+?) = -0.37 48 A ps vi 8X 0.3748 = 2.998 W
