In the circuit shown in the figure the neon lamp lights up if potential difference across it becomes 60 V and goes out if the potential difference falls below 30 V. The inductor coil has a very small resistance and emf of the cell is V = 4 volt. The lamp does not light when the switch is closed. The neon light flashes once when the switch is opened. Explain why?
