Question

what is the difference between ac and dc in the electrical system​

Answer 1

$\huge\boxed{\underline{\mathcal{\red{A } \green{N } \pink{S } \orange{W } \blue{E } \pink{R }}}}$

Direct current (DC) is the flow of electric charge in only one direction. ... Alternating current (AC) is the flow of electric charge that periodically reverses direction. If the source varies periodically, particularly sinusoidally, the circuit is known as an alternating current circuit.
