A full wave bridge rectifier is used to charge a battery of 24 V and 120 W-H. If the supply voltage with 220 V is used to feed the full-wave rectifier with 4:1 rectifier transformer, find: a) The diode conduction angle b) The value of current limiting resistor for 10 A (DC current) flows through battery c) The charging time in hours d) The power loss through the current limiting resistor e) The circuit efficiency
