Hello, I am a student and I have encountered some problems. Develop a circuit with a 10 kΩ potentiometer, 2 LEDs, transistors of the type BC 546 B, and resistors. The circuit should be supplied with 5 V voltage.
How the circuit works: If the resistance of the potentiometer is set to over 5 kΩ, a red LED with a diameter of 5 mm should be switched on. If the resistance of the potentiometer is set below 5 kΩ, a green LED with a 3 mm diameter should be switched on. Please help me.

 

Sounds like a homework problem. What have you tried so far? What class is this for?

Hello, this is a laboratory problem, I have not contacted the LED problem. I don't know how to design a circuit. Hope you can help me thank you for your reply.

Post a schematic for what you tried and tell us what didn't work.

For school work, you need to do most of the work; we can only offer guidance.

Thank you for your reply, I will discuss further with my classmates, I believe the answer is very close. Thanks for your help. Have a nice day.
