Simple DC Circuit

Conventional current flows from the positive terminal of the battery through the circuit toward the negative terminal.

Voltage (volts)

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..

Resistance (ohms)

Resistance is a measure of the opposition to the flow of current in an electrical circuit. It is influenced by the material's properties, length, cross-sectional area, and temperature.

Current (amp)

Electrical current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow.

Power (watt)

Electric power is the rate of transfer of electrical energy within a circuit.
