The four diodes used in a bridge rectifier circuit have forward resistances which may be considered constant at 1 ohm and infinite reverse resistance. The alternating supply voltage is 220 V r.m.s. and load resistance is 580 ohm. Calculate (i) mean load current and (ii) power dissipated in each diode.
