Question

An electric iron is based upon the principle of

• A. Heating effect of current
• B. Chemical effect of current
• C. Magnetic effect of current
• D. None of these

Answer 1

The correct option is A

Heating effect of current

Step 1. Explanation for the correct option

Option A - Heating effect of current

1. The electric iron works on the principle of the heating effect of current.
2. The metal in the electric iron gets heated when the current flows on it.
3. It is because the electric current flows through it, all the electrons present in the metal energize and get vibrated.

Step 2. Explanation for incorrect options

Option B.

The process of depositing a layer of any desired metal on another material using electricity is known as electroplating. It's one of the most common applications of the chemical effects of electric current.

Option C.

The magnetic effect of current is mainly used in making electromagnets and electric motors.

Therefore, an electric iron is based upon the principle of the heating effect of current.

Hence, option A is correct.
