What is the basic definition of dynamic electricity?

• A. The flow of current through circuits
• B. The energy stored in batteries
• C. The rate of energy transfer
• D. The resistance of a conductor

Answer: (A)

Dynamic electricity means electricity in motion—the flow of electric charges through a conductor. That movement is what we describe as current, the amount of charge passing a point per second in a circuit. So the basic definition is the flow of current through circuits.

The other ideas describe related but different concepts: the energy stored in batteries is chemical energy stored for later release, not the ongoing movement itself; the rate of energy transfer is power (how quickly energy moves, not the motion of charges); and the resistance of a conductor is a property that affects how easily charges flow, not the movement itself.
