Yep, today were gonna talk about schematic symbols.

Step 1: These Are Resistors

Step 2: These Are Polarized Capacitors

Fig.1 Is a polarized capacitor, which means that it has a - and a +. Examples of components: electrolytic capacitors. Fig.2 Is a fixed capacitor, which means that it doesn't have any polarity, or no - or +. Examples of components: mylar, ceramic, or sometimes electrolytic capacitors.

Step 3: These Are Transistors

As you can see in the picture, there are 2 kinds of transistors:(although the picture is missing 1 more transistor called a MOSFET or FET transitor.)NPN and PNP transistors.

Step 4: These Are Diodes

There are 3 kinds of diodes: rectifiers, zener, and LEDs.

Step 5: These Are Switches

Step 6: THE END
