Final answer:
Electric charge is an intrinsic property of an object or system that affects its interactions with other charged objects or systems. It is closely related to electricity as the flow of charge through a conductor creates electric currents.
Step-by-step explanation:
Electric charge is a property of an object or system that affects its interactions with other objects or systems containing charge. It is an intrinsic property, meaning it is a fundamental characteristic of particles such as protons and electrons. Charge can be positive or negative, and objects with the same charge repel each other while objects with opposite charges attract each other. Electric charge is closely related to electricity because the flow of charge through a conductor is what creates electric currents and allows for the transfer of electrical energy.
