Question
Which of the following effects can be produced by electricity?i) Heating effectii) Magnetic effectiii) Chemical effectOptions:i onlyi and ii onlyi, ii and iiii and iii only
Solution
The correct answer is i, ii and iii. Electricity can produce all three effects: heating, magnetic, and chemical.
-
Heating effect: When electric current is passed through a conductor (like a wire), it generates heat due to the resistance it encounters. This is the principle behind devices like electric heaters and incandescent light bulbs.
-
Magnetic effect: Electric current can also create a magnetic field. This is the principle behind electromagnets and electric motors.
-
Chemical effect: Electricity can cause chemical reactions to occur. This is used in processes like electroplating and electrolysis.
So, all three effects can be produced by electricity.
