Question

what is joules law ? give answer in simple language and fast.

Answer 1

Joule's laws are two: first about heat produced by an electric current, and second about how the energy of a gas relates to pressure, volume and temperature.

Joule's first law shows the relation between heatgenerated by an electric current flowing through a conductor. It is named after James Prescott Jouleand shown as:

{\displaystyle Q=I^{2}\cdot R\cdot t}

Where Q is the amount of heat, I is the electric current flowing through a conductor, R is the amount of electric resistance present in the conductor, and t is the amount of time that this happens fo

Answer 2

Joule's Law--

1)-It is the principle that at constant temperature the internal energy of an ideal gas is independent of volume.

2)-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.

3)-These internal energy of an ideal gas depends only upon its temperature irrespective of volume and pressure.

4)-Joule's Law states that H (Heat) = I (Current) x V (Voltage) x T (Time the current is allowed to flow). Or, written differently, H (Heat) = I2.
