Which term describes the energy that is used in these devices to produce the electric shock?

• A. Resistance
• B. Capacitance
• C. Current
• D. Inductance

Answer: (C)

Current is the quantity that describes how much electrical energy actually flows through the body during a shock. In these devices, energy is stored and then released as a brief current pulse that travels through the target. The amount of energy delivered depends on how strong that current is and how long it lasts, so the current flow directly drives the effect. Resistance affects the current for a given voltage, while capacitance and inductance describe storage and how the current changes, not the energy itself. So the term that best describes the energy used to produce the shock is current.
