what type of earthing do for dry fissure rock?
In Indian Household, generally we receive 220V AC single phase supply. But AC has 2 phases, +ve & -ve. So in +ve half cycle current is flowing...so what happens in the -ve half cycle?? Please illustrate.
An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull out torque will occur. The rotor resistance per phase is 0.3 ohm and motor stalls at 650 rpm. The slip when motor stalls is A 1 B 0 C 13.33% D 10.33%
