The fluorescent lamp L (of negligible capacitance) is connected in parallel across the capacitor C of a RC circuit. There is a current through the lamp only when the potential difference across it reaches the breakdown voltage VL;in this event, the capacitor discharges completely through the lamp and the lamp flashes briefly. Suppose that two flashes per second are needed. For a lamp with breakdown voltage VL 69.0 a 95.0 Videal battery, and a 0.130 HFcapacitor, what should be the resistance R of the resistor?

Explanation / Answer

VL = Vo (1- e^-t/RC)

VL = 69

Vo = 95

C = 0.13 x 10^-6 F

t = 0.5sec

put all in the above formulae

R = 2.968 x 10^6 ohm
