Heating effect of electric current can result in wastage of energy. Discuss.​

Explanation:

1) When an electric current flows through the conductor, a part of it is converted into heat energy. This is a waste of energy.

2) An additional cooling system needs to be added to the circuit to counter the heating effect. This adds to the cost.

The heating effect of electric current results in the wastage of energy in an electric bulb. In electric bulbs, the electrical energy is converted into light energy. A part of the electrical energy is converted into heat energy, which cannot be utilised

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
