Q. Open-circuit and load characteristics of generator?
The open-circuit and load characteristics of a separately excited dc generator, along with its schematic diagram of connections, are shown in Figures (a) and (b). It can be seen from the form of the external volt-ampere characteristic, shown in Figure (c), that the terminal voltage falls slightly as the load current increases. Voltage regulation is defined as the percentage change in terminal voltage when full load is removed, so that, from Figure(c) it follows that
Because the separately excited generator requires a separate dc field supply, its use is limited to applications in which a wide range of controlled voltage is essential.
Obtain expressions for the drain source current in an n-channel MOS transistor in terms of terminal voltages and transistor parameters. Indicate reasons why, for deep sub micron t
What is the difference between a hybrid pi and an re model?
Addressing Model As we have learned already that each instruction has two parts one is op code and another is operand. Op code specified the type of operations to be
Shunt Capacitors Line losses owing to poor PF can be decreased through improving the PF. Overall improvement in the operating condition can be brought about through reducing t
