Answer / vaansi

there will be deflection in ammeter

Answer / raju chintakindi

vamshi answer ammeter deflecting but, why because input is
DC and no frequency

Answer / vamsi

because u giving on and off power which is periodic like sinusoidal

Answer / bosky babu

If you switch ON & OFF periodically like a sinosoidal there will be a deflection in ammeter(If it is a low voltage, less than 5V).

Answer / g.v.k.chowdary

change in voltage will induces the EMF in the coil, so when we switch ON and OFF frequently there will be EMF induced and it will link with the secondary and there will be deflection in the ammeter. in case continously ON or continously OFF there will be no deflection.

Answer / arunraj

The ammeter shows deflections only if switch is repeatedly
ON and OFF.

Answer / jagadeesh

it works ausally when connected to primer y in series with
high resistance

Answer / teja

transformer wont work because their is no change in current

Answer / himansu

i think...teja is right....

Ceiling fan motor wiring Hi, I have 2 ceiling fans broken. The receiver/control units burned out due to lightening. One Harbor Breeze and one Hunter's I took them apart (remove receiver units). Now on both of the motor I see 4 wires coming out from each motor I really want to know the function of each wire. Are there anyway I can test to see which is which? After searching forums I know these 4 wires are from 2 sets of coils inside the motor, one is Start winding and the other is Runing winding I could not find the receiver/control unit any where, so I am planing to buy Capacitors and universal remote controls to make the fans run again. Anyone has any idea how to do the wiring, please help Thnks
