Answer:
There are two different types of current in widespread use today. ... In a direct current, the electrons flow in one direction. Batteries create a direct current because the electrons always flow from the 'negative' side to the 'positive' side. In a direct current, the electrons travel in one direction.

Answer:
The 2 types of current are Alternative Current (AC) and Direct Current (DC).
Alternative Current
- It is the flow of electric charge that periodically reverses direction.
- The frequency of AC can be anything, generally 50 Hz or 60 Hz.
- AC is safe to transfer longer distance even between two cities, and maintain the electric power.
- It was discovered by Nikola Tesla.
Direct current
- It is the flow of electric charge in only one direction
- DC has no frequency ( It has 0 frequency) .
- DC cannot travel for a very long distance. It loses electric power.
- It was discovered by Thomas Edison.
