Explain Joules laws and Joule's first-second law

Joule's laws (J.P. Joule)

Joule's first law:

The heat Q generated whenever a current I flows via a resistance R for a specified time t is specified by:

Q = I2 R t

Joule's second law:

The internal energy of an ideal gas is self-governing of its volume and pressure, based only on its temperature.
