Question

1. describe the current in direct current (dc):

the electrons dont move
the electrons move back and forth
the protons move back and forth
the protons move in one direction only
the electrons move in one direction only

Explanation:

In direct current (DC), the flow of electric charge (carried by electrons in conductors) is in a constant direction. Electrons are the charge carriers that move; protons are bound in atomic nuclei and do not move freely to contribute to current flow. So the correct description is that electrons move in one direction only.

Answer:

the electrons move in one direction only
