electronic symbols

Front

What is the symbol for a capacitor?

Back

A capacitor is represented by two parallel lines, which may be curved or straight, indicating its ability to store electrical energy.

Front

What is the symbol for a resistor?

Back

A resistor is represented by a zigzag line, indicating its function to resist the flow of electric current.

Front

What is the symbol for an inductor?

Back

An inductor is represented by a series of loops or coils, indicating its ability to store energy in a magnetic field.

Front

What is the symbol for a voltmeter?

Back

A voltmeter is represented by a circle with a 'V' inside, used to measure the voltage across two points in a circuit.

Front

What is the symbol for a switch?

Back

A switch is represented by a break in a line with a lever, indicating its function to open or close a circuit.

Front

What is the symbol for a fuse?

Back

A fuse is represented by a rectangle with a line through it, indicating its function to protect a circuit by breaking the connection when current exceeds a certain level.

Front

What is the symbol for a variable resistor (potentiometer)?

Back

A variable resistor is represented by a zigzag line with an arrow pointing to it, indicating its ability to adjust resistance.

Front

What is the symbol for a ground connection?

Back

A ground connection is represented by three horizontal lines stacked, indicating a common return path for electric current.

Front

What is the symbol for an ammeter?

Back

An ammeter is represented by a circle with an 'A' inside, used to measure the current flowing through a circuit.

Front

What is the symbol for a diode?

Back

A diode is represented by a triangle pointing to a line, indicating its function to allow current to flow in one direction only.
