Circuits and switches addresses AC Science Understanding ACSSU Electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources , through the context of simple electrical circuits and their components. Circuits and switches provides students with hands-on opportunities to:. In the Primary Connections approach, students are supported to create representations that draw on and strengthen their literacy development. In Circuits and switches , students represent and explain their understanding about how electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources, by creating these representations:.

## Electric circuit

In an electric circuit, electrical energy is continuously converted into other forms of energy. For example, when a current flows in a conductor, electrical energy is converted into thermal energy within the conductor. The electrical field, supplied by the voltage source, accelerates the free electrons, increasing their kinetic energy for a short time. This increased kinetic energy is converted into thermal energy through collisions with the ions of the lattice structure of the conductor. In Work and Kinetic Energy , we defined power as the rate at which work is done by a force measured in watts. Power can also be defined as the rate at which energy is transferred.

A source of energy is required to drive current round a complete circuit. This is provided by batteries in the circuits you have been looking at. The batteries convert chemical potential energy into electrical energy. The energy is used to do work on the electrons in the circuit. Power is a measure of how rapidly work is done. Power is the rate at which the work is done, work done per unit time.

## Circuits and Switches

Electric circuit , path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps , electric motors , or computers ; and the connecting wires or transmission lines. Electric circuits are classified in several ways. A direct-current circuit carries current that flows only in one direction. An alternating-current circuit carries current that pulsates back and forth many times each second, as in most household circuits.
