Question
How joules law of heating is related with work done
Open in App
Solution
Dear Student
When electric current is passed through a conductor, it generates heat dt offers to the current flow. The work done in overcoming the resistance is generated as heat. This generated heat can be given terms of Joule's law as
"Joules law of heating states that, the heat produced in a conductor by a constant current is equal to the product of the square of the current and resistance of the conductor and the duration of time the current passes."
That is, Q = I2 × R × t, where, Q is the heat produced in joules, I is the current through the conductor in amperes, R is the resistance of the conductor in ohms and t is the time in seconds.
