In the last five decades in India, there is a drastic change in production technology. The mineral-based oil like transformer oil is frequently...
by Tarun Agarwal 4 years ago What is an Open Loop Control System & Its Working The first control system was invented by “James Watt’s Flyball governor” in the year 17. The main intention of this device is to maintain the engine speed constant by changing the steam supply to the engine. At present, the control...
by Tarun Agarwal 4 years ago What is Voltage Follower : Working & Its Applications Operational amplifiers are frequently used in a voltage follower design. But, this is not the finest arrangement in terms of potential risk & capacitive loading of oscillations. These loads have a huge impact on the op-amp stability...
by Tarun Agarwal 4 years ago Types of Losses in a Transformer and Their Efficiency An ideal transformer is very efficient so they don’t have energy losses, which means the power supplied to the transformer’s input terminal must be equivalent to the power supplied to the transformer’s output terminal. So the input...
