Current to Voltage Converter Theory

The circuit shown here transforms a current into a voltage.The feedback resistor RF helps establish a voltage at the inverting input and controls
the swing of the output.The output voltage for this circuit is given by

Vout = IinRF
 

The light-activated circuits shown below use this principle to generate an output voltage that is proportional to the amount of input current
drawn through the light sensor.l.
