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
| Is This Answer Correct ? | 0 Yes | 0 No |
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.
