electric charge
Coulomb measures this
Electric charge is a fundamental property of matter that causes it to experience electromagnetic force.
Particles carry positive charge (protons) or negative charge (electrons).
Like charges repel; opposite charges attract.
Charge is measured in coulombs.
In everyday use, charge often refers to the amount of energy stored in a battery: My phone is low on charge.
