Power is measured in Watts (Joules / second). In electricity, power = current x potential difference. P=IV Watts = Amps x Volts ... Joules = volts x amps x seconds ... Therefore, the area of the strip = VDQ. The units of this will be joules, because wd = VQ.

We know that power is the rate at which energy is used. The amount of energy used is measured in JOULES. ... A 1000 watt fire will dissipate 1000 joules per second. With resistors, the greater the dissipation the hotter it gets, and the larger the resistor needs to be.
