The fan begins chattering or hamming.
why does the lamp bright when it is connected to the AC supply
The direction of the motor is dependent on the way the stator coils are wound.
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
opposes changes in current
Through loda
it will not work.
why the supply is given to the stator of dc generator give answer
there is a serpentine belt that powers the ac, fan , water pump, and all that.
You have a leak in the vacuum supply to the ac control.
Basically AC motors would not work on DC supply but there's however an exception for a Universal motor also known as a series motor. This is the only motor as far as I know that work on both AC and DC.
A lamp will only operate at its rated power at its rated voltage. So if you connected a 230-V lamp to a 110-V supply, its brightness would be very low. It does not matter whether the supply is AC or DC; a lamp would have the same brilliance at 230 V (AC) as at 230 V (DC).As a rule of thumb for fixed-value resistances, a 10% drop in voltage results in a 19% drop in power.
in our home most of the electrical appliances can work only on ac supply e.g. tubelights, fan, refrigeratorsand so on.else we can also say that dc supply is costlier then ac for the same amount of power.
