Charge is defined as what?

• A. A measure of the extra positive or negative particles that an object has.
• B. A form of energy stored in objects.
• C. The rate at which electric energy is transferred.
• D. A property that resists the flow of electric current.

Answer: (A)

Charge is the quantity that describes how much extra positive or negative particles an object has. It comes from an imbalance between protons and electrons, so a body with more protons than electrons has positive charge, while one with more electrons than protons has negative charge. The amount of charge is measured in coulombs, and it’s essentially counting these excess charged particles. This is different from energy stored in a system, which would be about how much energy the object contains; it’s different from the rate of energy transfer (power), and from resistance, which is how much a material resists current.
