primary of transformer connected to Dc supply in series with
switch, and secondary connected on ammeter, what happens
when swith On and OFF. (or) if continuously On and OFF
Answer Posted / 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.
