An electric heater is connected to the voltage supply. After few seconds Current gets its steady value then its initial current will be

A

equal to its steady current

B

slightly higher than its steady current

C

slightly less than its steady current

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
When the heater is connected to the supply its iniital current will be slighltly higher than its steady value but due to heating effect of the current the temerature will rise. This causes and increase in resistance and a slight decrease in current to steady current.
