Presentation transcript:

Physics Section 18.1 Draw schematic diagrams of electrical circuits A schematic diagram is a representation of a circuit that uses lines to represent wires and different symbols to represent components.

An electric circuit is a closed conducting loop which contains a source of potential difference and a load. A short circuit does not contain a load, resulting in an unsafe increase in current. A load is any component that dissipates energy, such as a light bulb, an electric motor, or resistor.

Wire the circuit shown in the schematic diagram.

The source of potential difference is called the EMF source. EMF is the electromotive force. It is the maximum potential difference in an open circuit. Assignment Page 645 Problems 1 - 5
