Here is your answer:

1. A alternating current is a current "is an electric current which periodically reverses direction." A direct current is a "current which flows only in one direction."

2. They are alike because both are "they both are able to travel in different directions." How they are not alike is that a "alternating current travels in a reverse direction but a direct current can only travel in one direction each current."

Hope this helps!

Answer:

A direct current or DC is when the current is a constant fixed number.  An alternating current or AC is when the current is alternating in a periodic manner.

Explanation:

Similarities

  • Both have the flow of electrons which produce current
  • Both are the source of providing potential difference

Differences:

Direct current flows in one direction while alternating current flows in both directions.
