WebAn alternating current can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC which always flows in a single direction as shown below. WebApr 24, 2024 · 1. The average value of alternating current measured in complete cycle is zero. 2. The average value of alternating current measured in half cycle is known as average value. The average value of alternating current is. I Avg. = 0.637 I o. This value is not in good agreement with practical value. 3.
WebThe RMS current value is I = 15.92 A The RMS voltage value is V = 220 V Therefore, the total power taken can be derived by the following equation: P = VI cos Φ Here, Φ is the phase difference between V and I In the case of a purely inductive circuit, the difference in the phase of an alternating voltage and an alternating current is 90°, WebApr 24, 2024 · Alternating current.
