A single phase inverter with an inductive load R = 20 22, L = 100 mH is supplied with a constant voltage source VG = 48 V. The switches operate such that the output is a square wave, whose first harmonic has an amplitude of 4VG/(2T). The switching frequency is 50 Hz. Find the RMS value of the first harmonic of the output current. ig VG a. O b. C.
