  • \$\begingroup\$ You will have to explain what you do know and where you need help. I mean, do you understand how all the individual components behave? Maybe the UJT is the problem as it is not a very commonly used component. Then look here: en.wikipedia.org/wiki/Unijunction_transistor \$\endgroup\$ – Bimpelrekkie Jun 6 '18 at 8:15
  • \$\begingroup\$ Would it help if I said that the value of R is << the interbase resistance Rbb of U1? You can look up a datasheet for a 2N2646 if you want a typical example of the UJT of olden times. \$\endgroup\$ – Spehro Pefhany Jun 6 '18 at 9:39
