Which rule states that electric charge is neither created nor destroyed but only transferred?

• A. Ohm's Law
• B. Conservation of Energy
• C. Law of Thermodynamics
• D. Law of Conservation of Charge

Answer: (D)

Charge cannot be created or destroyed; it can only be transferred from one object to another. This principle means that in any closed system, the total amount of electric charge stays the same even as charges move around. For example, when two objects touch or when charges flow through a circuit, electrons may relocate, but the overall net charge remains constant. This idea underlies the Law of Conservation of Charge, which specifically states that charge is conserved.

Other rules describe different relationships: Ohm's Law explains how current, voltage, and resistance relate, while the laws of thermodynamics and conservation of energy focus on energy, not charge.
