Average Voltage And Current

The average value of alternating current over a complete cycle is

Prove mathematically that the average value of alternating current over one complete cycle is zero.

What is the average value of a.c. over a full cycle ?

The average value of alternating current for half cycle in terms of I_(0) is

The rms and the average value of the voltage wave shown in figure are

The average value of an alternating voltage V=V_(0) sin omega t over a full cycle is

Define average value of alternating current . Derive an expression for it .

In an a.c circuit, value of voltage and current change every instant. Therefore, power of an a.c. circuit at any instant is the product of instantaneous voltages (E) and instantaneous current (I) . The average power supplied to a pure resistance R over a complete cycle of a.c is P = E_(upsilon). I_(upsilon) . When circuit is inductive, average power/cycle = E_(upsilon) I_(upsilon) cos phi , where phi is the phase angle between alternating voltage an altenating current in the circuit. In an a.c. circuit, 800 mH inductor and a 60 mu F capacitor are connected in series with 15 ohm resistance. The a.c. supply to the circuit is 230 V, 50 Hz The average power transferred per cycle t inductors is
