|
||||
| show | A device that converts energy from one from to another.
🗑
|
||||
| show | Converts electrical energy to light.
🗑
|
||||
| show | Convert electrical energy to light for such uses as a warning light on a car's dashboard.
🗑
|
||||
| show | Convert electrical energy to kinetic energy (motion).
🗑

| show | Converts electrical energy to sound.
🗑
|
||||
| show | A coil of wire that creates magnetic field when current passes through it.
🗑
|
||||
| show | Allows current to flow only when the button is pressed.
🗑
|
||||
| show | The circuit is normally closed (the device is on): the circuit is open (device is off) only when the button is pressed.
🗑
|
||||
| On/off Switch | show 🗑
|
||||
| show | Directs the flow of current to one of two routes, according to its position.
🗑
|
||||
| show | Often used to switch main electricity because it can isolate both live and neutral connections.
🗑
|
||||
| show | An electrically operated switch that may operate multiple switches at one time. Current flowing through a coils sets up a magnetic field, which causes the lever(s) to move, effectively changing the (relay) switch's position(s).
🗑
|
||||
| show | Restrict the flow of electrical current. They are rated in ohms and have color code on them to indicate their value, tolerance, and sometimes quality.

| Rheostat | show 🗑
|
||||
| show | A type of variable resistor with three contacts that's used to control voltage.
🗑
|
||||
| show | A device that operates with a small screwdriver or similar tool; it's designed to be set when the circuit is made and then left without further adjustment.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
