Electrical potential difference, often referred to as voltage, is the measure of work needed to move a unit charge from one point to another in an electric field. It is a fundamental concept in understanding how electric circuits function, as it drives the flow of electric current.

Electrical Potential Difference

Electrical potential difference

Voltage, also known as electric potential difference, is the measure of potential energy per unit charge between two points in an electric field. It is the driving force that pushes electric charge through a circuit, enabling the flow of current and the operation of electrical devices.

unit charge

An electric field is a vector field around a charged particle that represents the force exerted on other charges placed within the field. The strength and direction of the electric field are determined by the magnitude and sign of the charge, as well as the distance from the charge.

fundamental concept

An electric circuit is like a path that electricity follows to make things work, like turning on a light or making a toy move. It needs a power source, like a battery, to push the electricity around the path, and everything must be connected for it to work.
