What pushes electrons through a conductor?

Amperes
Watts
Volts
Ohms

The correct answer is: Volts

The correct answer is volts, as voltage is the driving force that pushes electrons through a conductor. Voltage, measured in volts, represents the electric potential difference between two points in a circuit. It acts like pressure in a water system; the higher the voltage, the greater the potential to push electrons through the conductor, facilitating the flow of current. In this context, while amperes measure the flow of electric current in a circuit, they do not indicate what causes the flow. Watts quantify the power consumed in a circuit, representing the rate at which electrical energy is used, but they rely on the presence of voltage and current. Ohms refer to resistance, which impedes the flow of current rather than pushing electrons forward. Thus, volts are essential to understanding how electrons are moved through a conductor, making them the correct choice.
