when generator of a power plant is not connected to grid , by increasing the mechanical torque speed of rotor increases but when it's connected to load instead of increase in speed current increases , why?
1 3606I want to ask that is there any relation between current denesity of copper and material purity. also is ther any standard which defines the standard current denesity of material.
1799actually i can't understand what is 3dB ? and it's really not clear to me.please any one let it me be cleared.
2081how to calculate the step resistance for slipring induction motor,how you deside the no of step for that?
2013we all know that in capacitor there will be no ay physical connection between the two electrodes of the capacitor ,and the charge is stored between these electrodes during charging , so with out any physical connection how these charge is transferred from one plate to the another plate during the discharge?????

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
