Circuit Symbols Quiz ResultsNearly 7000 readers took our quiz!
Electronic circuit symbols are used for drawing schematic diagrams. The symbols below represent electrical and electronic components. Here are the answers to our circuit symbol quiz.
This symbol represents a Single Pole Double Throw (SPDT) switch, which selects between two connections in a circuit. A switch breaks, interrupts, or diverts the current from one conductor to another.
This breaks, interrupts, or diverts the current from one conductor to another.
|SPDT Toggle Switch
A potentiometer is an adjustable resistor with three terminals in a circuit drawing. A "pot" provides a variable resistance.
A simple knob that provides a variable resistance.
This symbol represents a photodiode, which allows current flow only when exposed to light. It converts visible electromagnetic radiation (light) into either current or voltage.
Converts visible electromagnetic radiation into either current or voltage.
Light Emitting Diode
A MOSFET transistor is used to amplify and switch electronic signals and power. It uses an electric field to control the flow of electrons and shapes the conductivity of a channel. MOSFET = metal-oxide-semiconductor field-effect transistor
Uses an electric field to control the flow of electrons and shapes the conductivity of a channel. Pay close attention to this symbol!
