Hi everybody!
I need some help about a circuit analyse. You can see the circuit in the attachment. It is a 7805 regulator circuit. 7805 part allows max 1A out current, so the circuit is designed again with 2 pnp transistors to get a 5A out current. 4A current flows over the collector of the second transistor. Thus the out current reaches 5A (4A from the transistor + 1A from the 7805). Some information is given in the circuit and the wants are the values of the resistors in the circuit. I couldn't solve it . Please could you solve it and tell it to me clearly. And I will be so glad if you tell it over the picture. Thank you for your help.
