Question

Electronics

Hello.
The second day I struggle with the circuit in ewb, according to the assignment on the voltmeter, I should have about 5 volts, you can change the resistor values, but no matter how hard I try, I can’t squeeze out more than 3 volts ((

I circled something what can be changed.
If anyone will respond, I will be very grateful)
