Voltage is best defined as the pressure that pushes electrical charges through a conductor. This concept of voltage can be understood by considering it as the force or potential that drives electrical current from one point to another in a circuit. It is measured in volts and is crucial in determining how much current will flow through a circuit, given a specific resistance.

When voltage is applied, it creates an electric field that influences the movement of electrons, allowing them to flow freely through a conductor. This flow of electrons is what constitutes electrical current. Therefore, understanding voltage as a form of electrical pressure helps in grasping the fundamental principles of how circuits operate.

Other definitions, such as the flow of electrons or the amount of charge, describe different aspects of electrical circuits but do not capture the essence of voltage itself. Voltage is specifically about the potential difference that initiates and sustains the flow of current, rather than the current itself or the concept of charge. Similarly, resistance is a separate property that opposes current flow, further distinguishing it from the definition of voltage.
