Question

The energy conversion which takes place while discharging a mobile battery is from ________ to _________.

• A. Electrical, chemical
• B. hermal, chemical
• C. Chemical, electrical
• D. Thermal, electrical

Answer 1

The correct option is C Chemical, electrical

• Charging a mobile battery requires electrical energy which is supplied by a power source and further it is stored as chemical energy. Hence when we charge the mobile battery, electrical energy is converted into chemical energy.
• During the discharging process, i.e., when a mobile is not connected to a power source then this stored chemical energy in the battery is used to supply power to the mobile. Hence, while discharging the mobile battery, chemical energy is converted into electrical energy.
