Derivation of P=VI

1.	Derivation of P=VI
Answer» We know that energy = VITSO, P=W/T POWER=ENERGY ,P=VIT/T....( ONE TIOME IS CUTTED )P=VITHANKS Power = work / time So work = V×Q.( by formula of pd) And Q = IT ( By formula of electric current.) So p = V× I×T / T NOW T and T cancel .... So p = vi Proved..... Energy=VIT And power= energy/time So P = VIT/T =VI
