A half-wave rectifier circuit
A half-wave rectifier circuit is used to charge a battery
of e.m.f. 12 V and negligible internal resistance. The
sinusoidally varying alternating supply voltage is 24 V
peak. Determine the value of resistance to be connected
in series with the battery to limit the charging
current to 1.0 A. What peak current would flow in
the diode if the battery were reversed?
