Question

What happens if the current is allowed to flow through the circuit continuously for a long time? Why?

Answer 1

Answer:

• The wire will heat up because of joule's heating effect.
• The value of current will decrease because as the temperature of the wire will, so will the resistance and current will decrease.
• After a long time the temperature will become constant because the heat due to the joule's heating will be equal to the heat dissipated.

Answer 2

The wire will heat up because of joule's heating effect.

The value of current will decrease because as the temperature of the wire will, so will the resistance and current will decrease.

After a long time the temperature will become constant because the heat due to the joule's heating will be equal to the heat dissipated.
