what i did here is take current over the 4.7 kilo ohm and since there are no other voltage input other than the one then shouldn't the Vout be 0.2127 volts? thats not possible for a non-inverting amplifier right? do i just assume Vin = Vout in this case then?
That's just a unity gain amplifier. So gain=1, Vout=Vin. The 4.7k resistor doesn't matter, unless you get close to (or beyond) the supply voltages.
