The flowing of electrons through a circuit is known as which electrical quantity?

Voltage Resistance Current Charge

Correct Answer:

Current

Explanation:

Current is the flowing of electric charge through a circuit. It measures how much charge passes a point each second, with the unit the ampere (1 ampere = 1 coulomb per second). Electrons are the charge carriers in a conductor, so their motion constitutes current. It's helpful to remember that conventional current is defined as the flow of positive charge, which is opposite to the actual direction of electron flow. Voltage is the push that drives current, resistance opposes it, and charge is a property of matter, not the flow rate.
