1.A simple inverter imposes a square wave on a load. Filtering is accomplished by including a se-ries 25 mH inductor at the output. The load resembles a resistor. Given a 50 Hz circuit applica-tion, plot the amplitude of the wanted component of the output voltage as a function of the loadresistance in this case. Comment on load regulation.
