This energy is dissipated as heat. When a current of I I coulombs per second falls through a potential difference of V V volts, the rate of dissipation of energy is IV I V, which can also be written (by making use of Ohm''s law) I2R or V2/R I 2 R or V 2 / R. If two resistors are connected in series, the current is the same in each, and we see ...

Thermal Energy. From all the foregoing, it is clear that when an interaction can be completely described by a potential energy function we can define a quantity, which we have called the total mechanical energy of the system, Emech = K + U E m e c h = K + U, that is constant throughout the interaction. However, we already know from our study of ...
