Voltage is defined so that negatively charged objects are pulled towards higher voltages, while positively charged objects are pulled towards lower voltages. [15] [16] Therefore, the conventional current in a wire or resistor always flows from higher voltage to lower voltage.
May 9, 2024 · Voltage (also known as electric potential difference, electromotive force emf, electric pressure, or electric tension) is defined as the electric potential difference per unit charge between two points in an electric field. Voltage is expressed mathematically (i.e. in formulas) using the symbol “V” or “E”.
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current). So, when we talk about these values, we're really describing the movement of charge, and thus, the behavior of electrons.
If you want to reach beyond this intuitive description of voltage you can read this more formal mathematical description of electric potential and voltage.
Apr 20, 2022 · Voltage is defined as the pressure that is present to push electricity around a circuit or system. Voltage is quantified by the unit volt (V). The higher voltage the more electricity that can flow around a circuit or device, the lower voltage means that less electricity can flow around a circuit or electrical device.
Electric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy experienced by a test charge that has a value of + 1
Jan 28, 2019 · Voltage is a representation of the electric potential energy per unit charge. If a unit of electrical charge were placed in a location, the voltage indicates the potential energy of it at that point.
Voltage is what makes electric charges move. It is the 'push' that causes charges to move in a wire or other electrical conductor. It can be thought of as the force that pushes the charges, but it is not a force. Voltage can cause charges to move, and since moving charges is a current, voltage can cause a current .
Sep 3, 2021 · Voltage is the electromotive force or the electric potential energy difference between two points (often within the context of an electrical circuit) per unit of charge, expressed in volts (V). Voltage, along with current and resistance, describes the behavior of electrons.
