Power in AC Circuit: The Power Factor - Toppr-guides
WebIn 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. Most of the digital electronics that you build will use DC. WebJan 3, 2015 · During one half-cycle the field lines enter the area within the loop from one side of the loop, then things change and the magnetic field, for half a cycle, enters the loop from its under side.
