What is the formula of rate of dissipation of joule heat in resistance per unit volume ?
It will be most appreciated from my side if you give the derivation also ??
Hi Tejpal!
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.
Cheers!!
