Answer 2

The correct option about the one that works on the principle of heating effects of electric current is D) all the above.

• The electric heater, electric toaster and electric oven produce heat due to the heating effect of the iron coil.
• The resistance of the coil increases the heat produced in the electric toaster, heater and oven as the electric current is pass through the conductor. electric heat is calculated as per the formula: H = i²rt.
• Here, r is the res i is the current passed and t is the time for which the current is passed.
