Question

explain joule's law of heating​

Answer 1

Answer:

When current is passed through a resistance some work is done.In a passive resistance the work done is equal to the amount of heat evolved in a resistance. ... Let 'I' be the amount of current in the circuit. Let 'q' be the charge passed through the resistance in time't' second

${i}^{2} \times r \times t$

Answer 2

Answer:

joule's law of heating states that when the 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 sqare of the current,the resistance and time.

H= i 2 rt
