Question: Figure shows a load resistor R L = 20 connected to a high-pass filter consisting of an inductor L = 3.2 mH and a resistor

Figure shows a load resistor R_L = 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 R_L 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?
