A half-wave rectifier is charging a battery, which has 12 V as
its rated voltage. The battery is 85 %
charged at the initial charging time. At the end of the charging
period, the battery voltage is 115 %
of the rated voltage. Calculate the resistance value to limit the
charging current to a maximum of
10 A as the worst case. Get the power dissipated by the resistor
under these conditions. Get the
average current at the beginning and the end of the charging
process. Consider a 12 Vrms voltage
source at 50 Hz.
