Self Switching Power Supply
... This is achieved with the help of transistors Q1 and Q2, diodes D7 and D8, and capacitor C2. When a load is connected at the output, potential drop across diodes D7 and D8 (approximately 1.3V) is sufficient for transistors Q2 and Q1 to conduct. As a result, the relay gets energized and remains i ...

... The electrical power produced at Power Stations in Malaysia has a voltage of 11 kV. It is then increased to 275 kV or 500 kV by step-up transformer stations. The high-voltage electrical power is transmitted through overhead cables. The electrical power then enters the Switch Zone and is transmitted ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
