Hey Everyone,this is RenhotecIC,In this Instructable I will be going over the basics components of Electrical Engineering as well as there biggest uses in the industry.RenhotecIC will also give brief instructions on where to find and salvage them.

　　Step 1: Switches


　　Switches are one of the most basic electrical components but are also one of the most used in electrical engineering.

　　A switch responds to an external force to mechanically change an electric signal. Switches are used to turn electric circuits ON and OFF and to switch electric circuits. Basically what this means is that when you push down or flick a switch you are allowing current to flow through to the rest of the circuit.

　　Step 2: Diodes


　　A Diode is the simplest two-terminal unilateral semiconductor device. It allows current to flow only in one direction and blocks the current that flows in the opposite direction. The two terminals of the diode are called as anode and cathode. The characteristics of a diode closely match to that of a switch. An ideal switch when open does not conduct current in either directions and in closed state conducts in both directions

　　Step 3: The Resistor


　　The resistor is a passive two pole component used to limit the amount of current that is allowed to flow at any given time as well as the voltage. different resistors can resist more than others the way you work out a resistors resistance is by looking at the 4 stripes on the main body of the resistor the different colors show the resistance, to work out the color code.

　　Step 4: Batteries


　　An electric battery is a device consisting of two or more electro-chemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode, and a negative terminal, or anode. The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. These are especially handy when it comes to designing portable devices.

　　Step 5: Capacitor


　　A capacitor is a two-terminal, electrical

　　component used to temporarily store a charge in an electric feild. This is use full in Electrical Engineering because it can be used to smooth out varying DC supplies aswell as filtering circuits (high pass, low pass or band pass) they are even used as temporary batteries.

　　Step 6: Transistors


　　Transistors are is a small mostly 3 pole component made of elements in the group 4 in the periodic table, Silicon being the most common. To understand it think of it like this, Your brain has billions upon billions of neurons. The neurons let you think and remember things, Computers act the same way except the computers neuron is called a Transistor. The transistor acts either like an amplifier (Taking a small electric current at an input current and then produces a much bigger output current, you can see this at work in hearing aids or microphones) or like a Switch (taking a small current flowing through one part of a transistor can make a much bigger current flow through another part of it. Basically the small current switches on the larger one, this is how a computers chips work.)

　　Step 7: Potentiometer


　　A Potentiometer is a knob that has variable resistance which can result in the dimming of your lights or even sending information back to your micro controller this component normally has 3 poles also called a 3 pole resistor it works in the same way as a voltage divider except for the fact that this has variable outputs. You will often find these in house holds or sound controllers.

　　Step 8: Motors


　　Motors is a device that converts direct current into mechanical power. They rely on the forces produced by magnetic fields. It does this by having a coil of wire with a current running through it generates an electromagnetic field. The direction and magnitude of the magnetic field produced by the coil can be changed with the direction and magnitude of the current flowing through it.
