An electric heater is connected to the voltage supply After few seconds, current get 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
Answer
Equal to its steady current
Explanation
Solution
: When the heater is connected to the supply its initial currecnt will be slightly higher than its steady value but due to heating effect of the current the temperature will rise. This causes in resistance and a slight decrease in current to steady current.
