Compare between alternating current and direct current......​

Answer 1

$\huge{\boxed{\mathcal\pink{\fcolorbox{red}{yellow}{Answer}}}}$

Alternating current: (AC)

• It is a high voltage current
• Only use in high tension wires which have larger cross section area
• it's current flows periodically

Direct current: (DC)

• It is a low voltage current
• It is used in our home appliances
• it's current flows directly and for short term.

Answer 2

Answer:

InAlternating current, current keeps switching directions periodically – forward and backward. While in the direct current it flowsin a single direction steadily. The main difference between AC and DC lies in the direction in which the electrons flow.
