What is voltage?

What is voltage?

• A. The flow of electric charge
• B. The electrical potential difference between two points
• C. The resistance to electric current
• D. The capacity to do mechanical work

Answer: (B)

Voltage is defined as the electrical potential difference between two points in a circuit. It represents the force that pushes electric charge carriers, such as electrons, through a conductor, facilitating the flow of electric current. This potential difference is essential because it dictates how much energy per unit charge is available to do work in the circuit. The higher the voltage, the greater the potential for current flow, allowing electrical devices to function effectively. In the context of electrical systems, understanding voltage is crucial for grasping how circuits operate, how energy is distributed, and the relationship between voltage, current, and resistance as outlined in Ohm's Law. This definition aligns with the concept that voltage is essentially a measure of electric potential energy per unit charge, indicating the ability to move charges through an electric field.
