Question
Select the one in which the heating effect of current is not used.
- Electric geyser
- Electric iron
- A battery
- Electric immersion heater
Hint:
A battery
The correct answer is: A battery
An electric current is used to charge the battery and the electrical energy is stored in the battery in the form of chemical energy so the chemical effect of the current is used to charge the battery.
