Basics of Electronics

Electronics- It is one of the electrical technology. Its control & perform the electrons. nowadays, we can use the semiconductor components to perform the electron control.
Electronics devices & components:
Like capacitor,resistor,transistor,diode .... are all components used in Electronics. there are two types of components. Active & passive components.
Resistor-It is the 2-terminal component and its produces voltage is proportional to current through accordance which using Ohm's law. (i.e. V=IR). unit-ohm.
How to find the resistance value?
We have to identify from the color coding from the resistance.
Black-0*1, Brown-1*10,Red-2*100, Orange-3*1000,Yellow-4*10,000,Green-5*100,000,Blue-6*1,000,000,Violet-7*10,000,000,Grey-8*100,000,000,White-9
Tolerance or accuracy-Gold-5%, Silver-10%.
Capacitor-It is the passive electronic component, Its block the direct current while allowing Alternating current to pass, and to filter for other purposes used. Unit- farads.
Diode-It is the 2-terminal Electronic component,which conducting Electric current flows in uni-directional. It has 2-terminals P-N junction.
Semiconductor Diode-Like silicon is the semiconductor,which added impurities and one side contains negative charge(Electrons) is called N-type semiconductor. other side contains positive charge (Holes) is called P-type semiconductor.
Ohms law- If the current passing through the conductor is directly proportional to voltage(V), and inversely proportional to resistance(R).
i.e. I=V/R (Ohms law)
Transistor- It is the semiconductor devices which amplify the Electronic signals. It has 3-regions Emitter(E), Base(B) & Collector(C).
