Voltage is defined as?

• A. The rate at which current flows.
• B. The force that causes electrons to move from atom to atom in a conductor.
• C. The resistance of a circuit.
• D. The power delivered to a load.

Answer: (D)

Voltage is the electric potential difference that pushes charges to move through a conductor. It’s like electrical pressure that drives current when a path exists. The description that matches this push—the force that causes electrons to move from atom to atom in a conductor—is the best fit for voltage. By contrast, current is the rate of charge flow, resistance is what opposes that flow, and power is the rate at which energy is delivered to a load (P = V × I), which depends on both voltage and current.
