Homework Answers
a)
as we know
tan x = (Xc/ R)
tan x = 1/( 2 pi f C R)
f = 1/ ( 2* 3.14* tan 23* 3300* 3.5*10^-6)
f = 32.48 Hz
======
b)
capacitive reactance
Xc = R tan x = 3300 tan 23
Xc = 1400.8 ohm
net impedance
z^2 = Xc^2 + R^2
z = 3585 ohm
av power dissipated
P = V^2 cos x / Z
P = 135^2 cos 23 / 3585
P = 4.68 W
