Dynamic electricity is best described as what?

• A. Flow of current through a circuit.
• B. Nonmoving electrical charge.
• C. Magnetic field around a conductor.
• D. The energy stored in a capacitor.

Answer: (A)

Dynamic electricity means electricity in motion—the flow of electric charges through a conductor when there’s a voltage difference. That flow is what we call current, and it’s the moving aspect that defines dynamic electricity.

The other statements describe things that aren’t about motion. A nonmoving electrical charge is static electricity, which is charges at rest. The magnetic field around a conductor is a consequence of current, not the description of dynamic electricity itself. The energy stored in a capacitor refers to energy in an electric field, not the act of charges moving through a circuit.

So the best description is the flow of current through a circuit.
