The heating effect of electric current is used in
- Bread toaster
- Electric watch
- Switch
- None of these
Hint:
Bread toaster
The correct answer is: Bread toaster
Bread toaster is an appliance that works on heating effect of electric current and the filament of bread toaster has high resistance to provide high heat.
The toaster consists of the heating element. When electrical energy passes through this heating element, it converts this electrical energy to heat energy which helps to prepare toast.
