Question

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

When the heater is connected to the supply its initial current will be slightly higher than its steady value but due to heating effect of the current the temperature will rise. This causes an increase in resistance and a slight decrease in current to steady current.

equal to its steady current

slightly higher than its steady current

slightly less than its steady current

zero
