Hint: Alternating current (AC) is an electric current that regularly reverses direction, unlike direct current (DC) that flows in one direction only.
Complete step by step solution:
Alternating current: Electric current which reverses its direction at regular intervals many times a second, usually used in power supplies.
Direct current: Direct current is the electric charge of one directional or unidirectional flow.
The three differences between Alternating Current and Direct Current are given below:
From definition we know that, in alternating current, the flow of electric charges periodically changes its direction. AC is the most commonly used and preferred electricity for household appliances, offices, and buildings, etc. It was first tested using a Dynamo Electric Generator, using Michael Faraday’s principles in .
Note: The flow of direct current does not change regularly, as opposed to alternating current. In a steady voltage the current electricity flows in one direction. DC’s main use is to supply electrical devices with electricity, and also to charge batteries. Example: batteries for cell phones, flashlights, and flat screen TVs and electric vehicles. DC has a blend of plus and minus symbol, a dotted line or a straight line.

The three differences between Alternating Current and Direct Current are given below:
Characteristics | Alternating Current (AC) | Direct Current (DC) |
Possible volume of energy to carry | Move safely over longer distances in the area, which can provide more power. | DC voltage can-not go very far until it starts losing energy. |
Frequency | Depending on the nation the frequency of alternating current is | The direct current has zero frequency. |
Flow of Electrons | Electrons continue to turn directions-forward and reverse. | Electrons pass slowly or 'forwards' in one direction. |
