Question

what is joules law of heating write the mathematical form of this law​

Answer 1

Answer:

heat produced in a resistor is directly proportional to the square of the current for a given resistance ,resistance for a given current ,time for which the current flows through the resistor H=I2Rt

Answer 2

Answer:

Joule's law of heating states that when a current 'i' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time

Explanation:

Joule's law is given by:  Q = I2Rt Corresponding units: joules(J) = ampere2(A2) · ohm(Ω) · second(s)  Where:  Q is the heat generated I is the current(constant) R is the resistance of the conductor t is the time   The unit of the heat generated is joule, which can be rewritten as:  joule = kg · m2 / s2

hope it helps you
