... To allow current to flow through it, when light shines on it. (1) 5.0 x 10-4 V Vout = IR = 100 x 5 x 10-6 (1) = 5.0 x 10-4 V (1). As the photodiode is around the wrong way for this application (it should be reverse biased) it could be argued that a voltage equal to 5 V minus the cut in voltage is al ...
