Theories Used In Engineering

F=maV=IRP=(I^2)RFirst law of thermodynamics: The increase in internal

energy of a closed system is equal to the difference of the heat supplied to the system and the work done by it.

Zeroith law of thermodynamics: If two systems are each in thermal equilibrium with a third, they are also in thermal equilibrium with each other.

Law of conservation of energy: Energy cannot be created or destroyed, but it can be converted from one state to another.
