ok so the direction is from the photodiode to the inverting terminal.Hi,
The photodiode is marked for polarity, which indicates the direction of current.
Why would the current be AC in nature? You'll see some variance if measuring the output from a fluorescent tube, and some ripple if a tungsten bulb, but the output from the photodiode has to be DC (think about it).
