Joule's laws (J.P. Joule)
Joule's first law
The heat Q generated while a current I pass through a resistance R for a particular time t is given by following
Q = I2 R t
Joule's second law
The internal energy of an ideal gas is independent of its volume & pressure, depending on its temperature only.
Area of a Circle As a Limit Describing that the area of a circle is a limit of the sum of the area of interior triangles as the number of triangles goes to infinity.
