Common circuit symbols exist as a near universal language in electrical engineering and can save a lot of confusion. Having standard circuit symbols allows circuit diagrams to be drawn and understood around the world. In this activity, they will create a storyboard that matches each component of an electrical circuit with their symbol and use. This is a great way to introduce students to the symbols they'll need to master and draw when designing circuits.
| Wire | Wires are used to connect different components together. They are made of metal and allow current to flow through them. |
|---|---|
| Battery | A battery provides the push to move the charge around the circuit. |
| Resistor | A resistor is a component that reduces the current in a circuit. |
| Variable Resistor | A variable resistor is a resistor which can have its resistance changed. |
| Lamp | A lamp is a component with a filament that glows when a current is passed through it. Lamps can be used to see things in the dark. |
| Switch | A switch is a component that can break the circuit allowing other components to be turned on and off. A light switch is an example of a switch. |
| Voltmeter | A voltmeter is used to measure the potential difference or amount of push between two parts in a circuit. |
| Ammeter | An ammeter is used to measure the size of a current in a circuit. |
| Motor | A motor spins when it is connected to a circuit. It could be used to make a toy car move. |
