Power Amplifier

This circuit is used to save electricity in our homes to avoid spending too much . How it works ? This circuit of works to filter the AC voltage , and reduce the magnitude of the cosine curve AC current that will be read on the instrument KWH meters. KWH meters will work if there is a load wire passing through a coil of wire sensors to measure the AC current is passed, if the current through a lot of electricity. C1 and C2 worked as a deduction from stamping voltage if the switch is connected, so that equipment or components which enter the voltage was not much shocking. Part List : C1,C2 = 100pF / 400V or higher C3      = 10uF / 400V non polar capacitor Fuse   = 0.5W S1      = Switch on/off Use best quality capacitors Use the circuit on each item that requires AC power house to besaved using voltage field of electronics goods. Or if you take the trouble to make on each item , then use immediately near the KWH meter, to disconnect to tke...

Valid schematic circuit diagrams of fluorescent lamps with a voltage source using 12 volt battery. This circuit 12 volt fluorescent lamp is very useful if the power goes out or can be used in a dark place with no electricity , but can use  the battery 12V . This 12V fluorescent lamp circuit i have tried and the results are bright , durable until decades. You can use 12Volt fluorescent lamps up to 40W . Use quality 12 Volt fluorescent lamp, do not use the fast heat , because the fast was also damage the transistor at 12Volt fluorescent lamp circuit . Do not occasionally mistaken in putting up the transistor . Description for 12 volt fluorescent lamp Circuit Diagrams : R1 = 220R/0.5W R2 = 1/0.5W C1 = 100n/100V C2 = 220uF/50V Q1 = D1885/D1710 A/B= To A fluorescent lamp/ and B to B fluorescent Lamp and just use one pin B = Battery 12 volt with currents above 5A Roll of copper wire on ferrite rod, with : L1 = 1.2 mm diameter wire with many loops winding 20 times L2 = 1.2mm di...
