Hi everybody,.
i had puzzled for a long time and i con't convince myself that floating pin in a circuit can lead noise .. how could it come with open circuity??!!
can the Current flow through open circuit?
assuming the floating point of the switch and there's electromagntic fields already comes from phones,Ac,....etc
how can the current pass through this circuit ??!!!
as i read that floating pin can introduce noise or wark as antenna..but how come floating pin works as antenna while the antenna not closing the circuit??!!!
