Mean value of alternating voltage
WebJun 10, 2024 · The equation of alternating voltage is given by ν = 325.22 𝑠𝑖𝑛314𝑡. Find (i) RMS value (ii) Frequency (iii) Average value. Solution The maximum value of the voltage is V m … WebBoth AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.
