Current

Electric current is the flow of electric charge through a conductor, like water flowing through a hose. It happens when there is a difference in electric pressure, known as voltage, between two points. Electrons move from the area of higher voltage to lower voltage, creating a flow of current. The strength of this flow is measured in amperes (amps), while resistance measures how much a material opposes this flow. In a complete circuit, which includes a power source, conductors, and a load, the electric current can flow continuously.

Voltage is the electric pressure that drives the flow of electric current through a circuit. It creates a difference in electric potential between two points, causing electrons to move from the higher voltage point to the lower voltage point. Measured in volts, it determines how strongly the current will flow. Voltage is provided by sources like batteries or power outlets. Higher voltage means a stronger push for the current, which can power devices more effectively.
