Define electric power. An electrical device of resistance R isconnecte

1.	Define electric power. An electrical device of resistance R isconnected across a source of voltage V and draws a current I.Derive an expression for power in terms of current and resistance.
Answer» EXPLANATION: power is the RATE at which energy is being consumed. P=VI V=IR so, P=I(I)R
