What Is Voltage Difference
The potential difference is always less than the emf and the emf is the maximum voltage the battery can supply.
What is voltage difference. Voltage is the work to be done upon an unit charge to move between two points against a static electric field. Which says voltage is the difference in electric potential energy per unit charge between two points. V or volts or voltage. Voltage electric potential difference electric pressure or electric tension is the difference in electric potential between two points which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points.
Voltage also called electromotive force is the potential difference in charge between two points in an electrical field. The potential difference or voltage of a supply is a measure of the energy given to the charge carriers in a circuit. In the international system of units the derived unit for voltage potential difference is named volt. A voltage which is a measure of electric potential difference is the cause of electrical current to flow in a closed circuit.
A or amps or amperage. Current cannot flow without voltage. This reduced voltage is known as potential difference which depends on the connected load while the emf electromotive force is the unloaded voltage of the battery or power supply. In other words voltage is the energy per unit charge.
Voltage is referred to electricity where potential difference can be related to electrical magnetic and gravitational fields.
