Common Electronic Circuit symbols

Today, we recommend the most common linear electronic circuit symbols and diagrams. The Circuit-Symbols is very important in the circuit design or the circuit drawing. It is a pictogram that shows instead of various electronic devices. We will understand exactly the same. Also, we can make easily the electronics projects and repair jobs.

I have taught my son to learn basic electronics, which we try to bring the simple parts that can find them easily in general store so that they can be used to create simple projects.

Common-linear Circuit Symbols

Nowadays my son designs all the circuit diagram and illustrates on our websites. He likes and enjoys this job very much. After he did it often. It made his work better and faster.

The Most Linear Circuit Symbols that his design in easyeda.com He says that he likes easyeda.com because It’s simple, flexible, fast. Important updated version regularly and free too. The Figure below is also designed with easyeda.com for details on how to create each device. I suggest in my next article.

The Circuit symbols lists
Fixed Resistor_General Resistors
Variable Resistor_Potentiometer or pot trimmer
Resistors resist the flow of electricity. Most we use the resistors to divide a voltage into a smaller voltage.

Fixed Capacitor_Ceramic Capacitor, Mylar or Polyester Capacitor
Polarized Capacitor_Electrolytic Capacitors

LDR_Light Dependent Resistors
Another Variable Resistor is the light-dependent resistor (LDR). The LDR changes can conduct electric current with the changing of light.

Rectifier Diode (Silicon Diode)
The electrical current will flow through the diode as one-way valves. Most we use them in the rectifier and protect backward current spike.

LED_Light Emitting Diode

NPN Transistor_Very Popular
PNP Transistor_Not popular but importance!
Transistors are semiconductor devices with three leads. They are used as amplifiers and switches.

Solar Cell or Photo Diode
Positive supply (the Positive (+) voltage Connection)
Photo Transistor A transistor type that Light control current flow collector into the emitter
Connected Wires
Unconnected Wires
Ground Normal is the negative connection
SPST Switch_ON-OFF Switch
SPDT Switch_Selector
Normally Open Pushbutton Switch
Normally Close Pushbutton Switch
Relay_Switch is controlled by electric current
Speaker_Convert audio to sound
PIEZO Speaker Emit tone sound
Meter_Measure the current and voltage
Lamp_Change electricity to light
Battery_Power source
OP-Amp_Integrated Circuit
