I understand that

  1. R1 and R2 make a voltage divider.
  2. initially Q1 is not conductive, so is Q2?
  3. initially C1 acts as short circuit, so flashes the light L1 for a moment?

Please correct me if wrong. Can someone breakdown this circuit step by step? Is there an easy analogy to solve such combinational transistor circuits generally?

  • \$\begingroup\$ ok. So the initial voltage is not high enough to light up L1? would you please mind breaking down the working of the circuit step by step? \$\endgroup\$ Commented Sep 17, 2021 at 13:45
  • \$\begingroup\$ It is a very good start. But, it takes a little more than that .To get insight & understanding of how the circuitry works, try Circuit Simulators. \$\endgroup\$
