Heat in electricity formula
WebThe longer the time the larger the amount of heat produced The amount of current, I. the higher the current the larger the amount of heat generated. Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t … WebPower is defined as the rate energy ( \text U U) is transformed or transferred over time. We measure power in units of joules/second, also known as watts. An electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge.
