hello there.. i currently have a little bit confuse
how to measure the source current and sink current in 741 op-amp circuit. so i need some help from you all.
from my understanding, source current is the current output from the output terminal while sink current is the current input to the output terminal. i have check all the manufacture for this 741 op-amp, but cannot find the specification value for source and sink current.
here i attact my measurement circuit for source current and sink current.
source current measurement circuit
my ideas is:
V2 = Vcc/2 - __V
sink current measurement circuit
(i dont really know how to measure the sink current for this circuit)
P/s: I am a new beginner, sorry if the question that i'm asking is too general.
is it "source current" term@definition is same with "current source"???

source current measurement circuit
my ideas is:
- give a single supply for these op-amp.
- input voltage V1 and V2, i have to vary till get high output voltage
V2 = Vcc/2 - __V
sink current measurement circuit
- also give a single supply for these op-amp.
