hye everyone,im new im stucked with thi smedical Instrument homework where my lecturer want me to construct a current to voltage converter circuit using OP07CP and photodiode,,but in Multisim software, my lecturer said i can't directly take the photodiode to the circuit because i dont have any light source, so he suggest to use opto-transistor whether phototransistor or optocoupler..but how can i draw it in Multisim???? help me find this out,,, :(

A current source is a basic signal source component in Spice (Multisim). It will be found in the same location in the software tab as a voltage source.
