A three phase transformer 460v primary 220v secondary (three phase four wire system.) Why did we get 460 volts across the neutral on the secondary side?
If a 1.5V,3W torch light bulb is connected in series with a 15HP/11.19KW,230V single phase motor and the combination is connected against a 230V supply and switched on than what will happen keeping all other parameters as it should be A)the bulb will glow normally B)the bulb will not glow C)the bulb will glow with extra brightness D)the bulb will burn out and if a fuse is connected to the above circuit will something happen to the fuse and what about the single phase motor will it be affected?
