Supose we have one 220v A.C fan.if we provide 220v D.C what
will be happen?
Answer Posted / achuthan
The magnetic core will get saturated and fan would burn.
Curret i(t)= voltage(t)/ resistace as a generalal case. In
caseof AC it could be considered as V/Z ( where
Z= R+j2 pi f L).In the absence of AC thre will not be
frequency " f". In addition the current would come down
only if the fan rotates. It would not rotate due to split
phase requirement etc and the stater would draw high
current. It is advised to ref some fundemental book and
understand as to how single phase motor converts electrical
energy to mechanical energy.
