Question

discuss two forms of current (ac and dc) write its sources and application

Answer 1

Answer:

Explanation:

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. ... The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage

Direct current is the unidirectional flow of an electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams...
