$\Large\bold{\mathbb{\colorbox{black}{\green{Produces heat}}}}$

When current is switched on in a room heater, it produces a heat due to the heating effect of current passing through the conductor.

Note: Fuse can here act as a safety device for the heating effect of electric current. Mostly high resistance wire such as Nichrome is used in an electric heater.

Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or joules.
