Sir protective resistance kaise motor ko protect kar rha he please bata dijiye

[@classyartist6233]

Thanks sir

[@mrinmaygiri9843]

Main advantage is that we can control speed(above normal) of a dc shunt motor by varying the resistance which is in series with the field winding, that we can't in 3point starter.
