Component has a x% tolerance: What does this mean exactly?
All components have specification tolerances and ranges. Some examples are:-
Resistor 1%
Electrolytic capacitor 20%
Zener diode breakdown voltage 5%
Clearly it kinda indicates that the specification may vary by x% from that stated. So a 5%, 24V…

Constant current circuitry tolerance dependency
I have the below given circuitry. The circuit provides ( 12 - 3.3 = 8.7 V) 8.7 V / R3 of current.
My specific question:
What is the effect of PNP transistor on the variation of current?
Until now I have following cases:
more current case: R1…
