AKS 10b

Develop and use models to illustrate and explain the conventional flow (direct and alternating) of current and the flow of electrons in simple series and parallel circuit.

​Also called a voltage source, this is the component that supplies the energy to the circuit. Examples of power sources include batteries and generators.

Power Source

This is the device that uses the electrical energy in the circuit, such as a light bulb, motor, or resistor.

Load

This is the path that the current flows through, connecting the power source and the load. This can be made of wire or printed circuits on a circuit board.
