Electrical symbols
Scientists and engineers working with electrical circuits require a shorthand and recognisable set of codes to make their work easier to understand. Below is a table of symbols with their titles and descriptions.
| Symbol | Title | Descritption |
|---|---|---|
 | Wire | The connecting cable that is used to make circuits |
 | Cell | A chemical store or electricity that can be converted to electrical energy |
 | Battery | 2 or more cells connected in series |
 | Voltmeter | A meter put across a component to find out how much energy it is using |
 | Ammeter | A device used to show how much current is flowing in a part of a circuit |
 | Ohmmeter | A device to measure the resistance of a component in a circuit |
 | Open switch | A device that casues a break in a circuit |
 | Closed switch | A device that allows the completion of an open circuit |
 | Motor | A device that converts electrical energy into motion |
 | Speaker | A device that converts electrical energy into sound energy |
 | Lamp | A device that converts electrical energy into light energy |
 | Buzzer | A device that converts electrical energy into sound energy |
 | Resistor | A device that converts electrical energy to heat energy |
 | Variable resistor | A device that can change the amount of resistance in a circuit |
 | Fuse | A device that prevents too high a current in a circuit |
 | Power supply | A device that can be plugged in to the mains electrical supply to provide a direct current supply |
Crossword Exercise
In the crossword below the cluse are images and you are to enter the title of the symbol into the grid. Click on the number in the grid to reveal the picture related to the crossword entry.
Please be aware that where you have a symbol for a two word symbol title, the crossword removes the space between the two words. So an open switch becomes openswitch. Rembmer it is better to try to remember what the symbols are, and not to look back in the table. Once you have completed all the symbols that you can do you should review the ones that you don't know.
Please be careful with spelling, because crosswords need all of the correct letters in the right order.
