Electrical Circuit Diagram Pdf
Being able to use the correct technical terms associated with residential electrical wiring. Understanding how electricity is distributed and controlled throughout your home. Recognizing the different kinds of circuits that may be found in your home. Reading and creating wiring diagrams and understanding the associated symbols.
Circuit diagrams or schematic diagrams show electrical connections of wires or conductors by using a node as shown in the image below. A node is simply a filled circle or dot. When three or more lines touch each other or cross each other and a node is placed at the intersection, this represents the lines or wires being electrically connected at that point. Wiring examples and instructions with video and tutorials. My site is dedicated to helping you get connected. Whether it's trying to figure out that rat's nest behind your television set or just simply changing over an electrical wall switch or outlet, I'm here to help. Electrical circuit An electrical circuit is the complete loop through which an electrical current flows. It is made up of a series of electrical components and conductors (e.g., batteries, electrical wires, light bulbs, etc.). The current only flows in an electrical circuit when the path is completely closed, forming a loop. CLASS NOTES-1.

Okay, so now that we've gone through the basics, lets try to read a real world schematic of a circuit. so lets dissect this circuit!
*I have numbered each symbol so that we stay on the same page while im describing each part
the first symbol you see is the one with two horizontal lines, one smaller than the other. do you remember what this is? you can always look back at the guide. its a battery. in this case a nine volt battery. if you look back at the polarity chapter you will see that the longer line represents the positive terminal of the battery.
next you can see that there is a line connecting the positive side of the battery to the second part which if you look back at the guide you will find is a switch with two positions: closed (on), and open (off). seems backwards? its not because if you think of that little door like thing on the symbol closing than it would complete the circuit, thus being 'on'.
so when we flick the switch closed where does the electricity go next? that squiggly line is a resistor. this is a symbol you REALLY want to memorize. they are in almost every circuit. basically in just makes sure that the not too much power from the battery is sucked up by the next part by resisting the flow of electricity.
so the final part is the triangle thing. that is a diode (as you can see on that handy chart in this ible). in this case a light emitting diode, or LED. remember LEDs are polarized so when you actually go to make this circuit make sure you put it in right.
finally you can see that the negative side of the LED connects back to the negative battery terminal and the circuit is complete!
THERE IT IS! a flash light! you can now continue on to building the actual thing!
building this circuit will bring its own challenges. so, if you want to be walked through check out my instructable: 'making circuits: the beauty of breadboards'. Drivers for external dvd player. it will go through the exact steps of building this flashlight, including where to buy parts for cheapest. but also teach you more important knowledge for building all sorts of circuits. (i did actually make this one)
important note, the schematic will not tell you all you need to know. in most there will be text seperate telling you exactly what parts to buy, you cant just throw in any resistor or any capacitor and whatnot. i have the details for the parts in this project in the next instructable mentioned above.
PLEASE RATE AND COMMENT
this is my first ible, i need feedback
