Question

define joul law?????​

Answer 1

Answer:

The law that states, the heat produced by an electric current i flowing through a resistance for a given time t is directly proportional to i2 Rt

Answer 2

${\huge{\bold{\blue{\underline{♡AnSwEr-♡}}}}}$

$<b>{The principle that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current.}$

$<b>{Joule's law of heating states that when acurrent 'i ' passes through a conductor of resistance 'r' for time 't' then the heatdeveloped in the conductor is equal to the product of the square of the current, the resistance and time.}$
