hiii guys
i really need a help in my FYP , and its about non contact current sensor which is " Rrogowski Coil "
just to make it short
i have already design the coil and also the amplifier
the coil already work for high frequency ( 1 M ) and the result is 24mV, but my project is about low frequency between ( 1 f - 1k f )
so, i design the amplifier
which is non-invierter and my ( Rf = 100 K ohms , Ri = 1 K ohms )
so, my Gain is ( G = 100 )
when i pass 1M frequency through the coil and i connect the coil to my op-amp
but i dont get any result
could any 1 help me on that ?????????
why there is no result even the Gain is 100
