joules law of heating effect or heating effect of current

the amount of heat produced in a coil is directly proportional to the

# square of the current

# resistance

# time in which current flow

i hope it is usefull for you

thanks

Answer 2

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.

 

H = i 2 rt
