Question

explain joules law ?????​

Answer 1

Answer:

Joule's law, in electricity, mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy. ... He determined that the heat evolved per second is equivalent to the electric power absorbed, or the power loss.

either of two statements in physics: (1) the rate at which heat is produced by a steady current in any part of an electric circuit is jointly proportional to the resistance and the square of the current (2) the internal energy of an ideal gas depends only upon its temperature irrespective of volume and pressure — ...

Answer 2

Explanation:

Joule’s law, in electricity, mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy. The English physicist James Prescott Joule discovered in 1840 that the amount of heat per second that develops in a wire carrying a current is proportional to the electrical resistance of the wire and the square of the current. He determined that the heat evolved per second is equivalent to the electric power absorbed, or the power loss.
