DC Electric Power
The electric
in watts associated with a complete electric circuit or a circuit component represents the rate at which energy is converted from the electrical energy of the moving charges to some other form, e.g., heat, mechanical energy, or energy stored in electric fields or magnetic fields. For a resistor in a D C Circuit the power is given by the product of applied
watts = volts
x amperes

Power Dissipated in Resistor
Convenient expressions for the
dissipated in a
can be obtained by the use of .
These relationships are valid for AC applications also if the voltages and currents are
or effective values. The resistor is a special case, and the
expression for the general case includes another term called the
which accounts for
between the voltage and current.
The fact that the power dissipated in a given resistance depends upon the square of the current dictates that for high power applications you should minimize the current. This is the rationale for transforming up to very high voltages for cross-country .
