Make very easy and chip rate Inverter ----------------------------------------------------------------------------------- It is very easy circuit Use transistor npn BC547       pnp BC557 bipolara npn H13003 Use capasistor 100uF Use resistor 10K ohms ----------------------------------------------------------------------------------- INVERTER This inverter can't make sign wave this look like sign wave but not sign wave. This inverter making signal oparator low power appliances run on this inverter.

Make very simple amplifire Use Resistor - 4.7K ohms - 22K ohms Use capacitor - 47uF - 100uF Transistor - BC547 - 2N3055 35W An  amplifier  is an electronic device that increases the voltage, current, or power of a signal.  Amplifiers are  used in wireless communications and broadcasting, and in audio equipment of all kinds. They  can  be categorized as either weak-signal  amplifiers  or power  amplifiers . The power  amplifier works  on the basic principle of converting the DC power drawn from the power supply into an AC voltage signal delivered to the load. Although the amplification is high the efficiency of the conversion from the DC power supply input to the AC voltage signal output is usually poor. Amplifiers  are usually designed to function well in a specific application, for  example : radio and television transmitters and receivers, high-fidelity ("hi-fi") stereo equipme
