Activity Overview
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.
Circuit Component Symbols Example
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. |

Student Instructions
Create a T-Chart that matches components of an electrical circuit with their symbols and uses.
- Click "Start Assignment".
- Find the circuit symbols by searching "circuits" or "science".
- Put each of the circuit symbols in the cells on the left.
- Identify each symbol by replacing "TERM".
- In the right hand column, create a visualization and write a sentence to describe what the component can be used for.
