When we apply a voltage to a

**resistor**, current flows and energy is dissipated. Forexample, when we apply 10 volts to a 10-ohm, ^-watt

**resistor**, a current of 1ampere flows; also, a power of10VX 1A= 10Wis dissipated, and the

**resistor**smokes.

In Figure 14.2 we have a battery Vthat provides power to a

**resistor**R. Since Eand J are in opposite directions in the battery, E • J is negative there; so instead

of removing power as Joule heat, the battery is providing electromagnetic energy

to ...
