9 12200Iam deepthi.i completed my b.tech from electrical engineering.i want to prepare for civil services.i dont have much knowledge about these exams,but i have great zeal of cracking exams.plz provide me suggestions to which options i can select for optionals
7 9955i want to know is it possible to generate usefull power by coupling generator with motor & supply gives to motor by battery source then generator generates power. remove the battery source given to the motor & feed the supply from some of the generated power supply to the motor & motor runs continously. generator generate power contnously.is it possible ?

Determine a suitable number of slors and conductors per slot for the starter 1 winding of a 3 phase, 3300 V. SO Hz 300 rpm alternator. The diameter is 2.3 m
In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
