 Transistor is the main component of all devices and circuits.This is by semiconductor and work as a switching in your device or circuit. All the circuits are not possible to make without transistor. The above image shows D882 Transistor this transistor is very common to use and very low price in local market this Transistor price is only 5 Rs this is very chip price. By using this Transistor you can make a simple inverter at your home.

Simple inverter Circuit diagram


inverter circuit board diagram,inverter circuit digram for home

So you can see the above diagram is present a simple circuit connections that's show how to make inverter :-

Components:

1. D882/BD140 transistor.
2. 220 ohm resistance.
3. 1K resistance.
4. 100uf capacitor.
5. Mobile Charger Transformer.
6. 3v battery.
7. Bulb Holder.
8. Connecting wires.

For making this circuit you can also use BD140 Transistor 
BD140 Transistor is best for this circuit and give more out put. This Transistor price in local market is 10 Rs so this is also chip price and pin out show given below digram
bd140 transistor circuit,bd140 pinout, bd140 transistor price


There pin out is same but BD140 is pass more voltage and amp and D882 is pass less voltage and amp so the Result is D882 Transistor is give less out put and BD140 Transistor is give more output AC voltage.

Question Bank Principle of an optical fiber (total internal reflection)  1. Explain briefly 'basic principle of an optical fiber'. Ans. Optical fibres works on the principle of total internal reflection. When light ray strikes at the internal surface of optical fibre cable called such that incidence angle is greater than critical angle, then incident light ray reflects in the same medium and this phenomenon repeats. or Explain the principle of total internal reflection. Ans. Total internal reflection: When a light ray travels from denser medium to rarer medium, the angle of incidence is greater than critical angle then it reflects into the same medium. This phenomenon is called total internal reflection. Acceptance angle and Numerical aperture 2. Explain the terms numerical aperture and acceptance angle. Ans.The numerical aperture is determined by the core and cladding. The acceptance angle is determined by core, cladding, and the outside. The greater the difference in the inde
