A moving coil ammeter, a thermal ammeter and a half-wave rectifier are connected in series with a resistor across 110 V a.c. supply. The circuit offers a resistance of 50Ω in one direction and an infinite resistance in the reverse direction. Calculate (i) the readings on the ammeters and (ii) the form factor and peak factor of current wave. Assume the supply voltage to be sinusoidal.
