Question

question 16
an electric current is
a. a type of electric field.

b. a flow of particles with electric charge.

c. a power source for an electric charge.

d. a count of how many positive or negative particles are in an electric
charge.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: An electric field is a region around a charged particle where a force is exerted on other charged particles. An electric current is not a type of electric field. So A is incorrect.
• Option B: By definition, an electric current is the flow of charged particles (usually electrons in a conductor). This matches the fundamental concept of electric current.
• Option C: A power source (like a battery) provides the potential difference to drive the electric current, but the current itself is not a power source for the charge. So C is incorrect.
• Option D: Electric current is the rate of flow of charge, not a count of the number of charged particles. So D is incorrect.

Answer:

B. a flow of particles with electric charge.
