Question
For a constant resistance, the correct relation between heat produced (H) and electric current (I) flowing is:
Answer: Option C
:
C
According to Joule's law, theheat produced in a resistor is;
(i) directly proportional to the square of current for a given resistance.
(ii) directly proportional to resistance for a given current.
(iii) directly proportional to the time for which the current flows through the resistor.
That is H=I2×R×t
HenceH∝I2 is the right relation.
