Question
Which of the following best describes a direct current?(1 point)
Responses
the flow of electric charges through a conductor
the flow of electric charges through a conductor
an electrical current that flows in alternating directions back and forth
an electrical current that flows in alternating directions back and forth
an electrical current that flows in one direction
an electrical current that flows in one direction
a stationary electrical charge
a electrical current that flows in one direction
The correct answer is: an electrical current that flows in one direction.
To determine the correct answer, we need to understand what a direct current is. A direct current (DC) is an electrical current that flows in one direction.
Looking at the given options, the first option describes a direct current - "the flow of electric charges through a conductor." This means that electric charges are moving in one direction along a conductor, which matches the definition of a direct current.
Therefore, the correct answer is:
- an electrical current that flows in one direction
