- Power dissipated in a resistor
Combining the above two equations and putting them in terms of the I and R: - Power dissipated in a resistor in terms of the current [watts or joules/sec]
For more information on Power see Power (physics). Finally the amount of power dissipated by a resistor is the amount of work done on the resistor (ie. heat dissipated in the resistor) divided by the length of time: Which therefore gives: Note that Joule's ## See also |
