In a.c. circuits power consumed is
WebPower of a circuit is defined as the rate of consumption of electric energy in that circuit. It is given by the product of the voltage and current. In an AC circuit, the voltage and current vary continuously with time. Let us first calculate the power at an instant and then it is averaged over a complete cycle. WebSimilarly, the power is the same in the AC circuit also, the only difference is that in the AC circuit the instantaneous value of voltage and current is taken into consideration. Therefore, the instantaneous power in a purely resistive circuit is given by the equation shown below: Instantaneous power, p= vi. The average power consumed in the ...

Did you know?
WebThe concept of power dissipation in AC circuit is explained and illustrated with the example. For instance, a power factor of 0.68 means that only 68 percent of the total current supplied (in magnitude) is actually doing work; the remaining current does no work at the load. Reactive power [ edit] WebSo we can write power consumed in an AC circuit is: Note: Since P= V x I. So, If V=0 or I=0 then P=0. Also If V & I both are positive then P will be positive and If anyone of either V & I …
