On what factors the generating voltage depends ? Generating voltage are (3.3kV, 6.6KV , 11KV, 13.8kV) Why so ?
Bhel,
5 13115Hi I'm doing my MBA(3rd semester).I applied for the post of ET conducted by BHEL the last year.I cleared the written and lost in personal interview.Again I wrote the exam this time and cleared the written n yet to take the personal interview.Shall I disclose in the interview about my studies.What shall i say if they ask about my change from studies to job
Bhel,
2115If current flows through conductor it produce magnetic field only.but if current flows through vaccum both magnetic & electrical field produce why ?
NTPC,
4 7004Hi, We facing one similar problem in our computers i.e we are newly constructed our design department after that shifted our computers but our computer desktop screen is vibrating. we are conducted our electrical maintainance person he told that is UPS problem, then we changed the UPS also again we are facing that problem in that room only. then we put lcd monitors that problem is solved. But in other monitors why the computer desktop screen is vibrating please give a suggestion to me. Regards, Raju.N.G

How stabilizer works??
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
