Question:
Figure shows a load resistor RL = 20Ω connected to a high-pass filter consisting of an inductor L = 3.2 mH and a resistor R = 4Ω. The input voltage is ← = (100 V) cos (2πft). Find the rms currents in R, L, and RL if
(a) f = 500 Hz and
(b) f = 2000 Hz.
(c) What fraction of the total power delivered by the voltage source is dissipated in the load resistor if the frequency is 500 Hz and if the frequency is 2000 Hz?
