Which flows through the other?

A. an electric current through an electric charge
B. electrons through electric charges
C. an electric charge through an electric circuit
D. an electric circuit through an electric current

To determine which option correctly describes the flow of electricity, we need to understand the concepts involved.

An electric current is the flow of electric charge in a conductor. Electric charges, specifically electrons, are particles that carry the electric charge. An electric circuit is a closed path through which electric charges can flow.

Now, let's analyze each option:

A. an electric current through an electric charge: This statement is not accurate because electric current does not flow through an electric charge. Instead, electric charge is carried by particles such as electrons.

B. electrons through electric charges: This statement correctly describes the flow of electricity. Electrons, among other charged particles, are the ones that flow through electric charges.

C. an electric charge through an electric circuit: This statement is not accurate because electric charges do not flow through an electric circuit. Rather, an electric circuit provides a pathway for the flow of electric charges, specifically electrons.

D. an electric circuit through an electric current: This statement is not accurate. An electric circuit does not flow through an electric current. Instead, an electric circuit is formed by the arrangement of interconnected components that allow the flow of electric current.

Therefore, the correct option is B. Electrons flow through electric charges. This option accurately describes the movement of electric charge (in the form of electrons) in an electrical circuit.
