Hi all,
i have made a small circuit which work properly in stimulation but when tested pratically it does not work. (Circuit Diagram attached).
Its just a small circuit which i made it for a basic knowledge of level shifting.
m problem is when the switch is close, R25 shows me 24V but after R25 and at base of Q8, i dont get any voltage due to which the transistor does not gets on. and collector emitter voltage always remains 5V.
the transistor Q11 works properly, it gets ON and OFF when swtich is triggered accordingly.
Can anybody please let me know what the issue is with the circuit.
