Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, … WebThe average power of an alternating current circuit can be calculated by calculating the instantaneous power of the circuit. In an AC circuit, the average power dissipation can be calculated by, P a v = ∫ 0 T V I d t ∫ 0 T d t The instantaneous e.m.f and the current in an AC circuit are given by: V = V 0 s i n ω t I = I 0 s i n ( ω t − ϕ) تويتر ادعيه https://liverhappylife.com
