WebTypical Photodiode Transfer Function. Current flows from cathode to anode when light strikes the photodiode’s active area. Ideally, all of the photodiode current flows through the feedback resistor of Figure 1, generating an output voltage equal to the photodiode current multiplied by the feedback resistor. WebA) R1 is a CdS photocell in series with a 1000-ohm resistor. The 5 volts form VCC divides across R1 and R2 in proportion to their resistance. For example, if R1 = R2, one would read 2.5 volts across each component. Using a DC voltmeter (black lead on ground, red lead at V) one will read 2.5 volts.
