Please solve this question in detail.

The gure shows the circuit of a ashing lamp, like those attached to barrels at highway construction sites. The uorescent lamp L (of negligible capacitance) is connected in parallel across the capacitor C of an RC circuit. There is a current through the lamp only when the potential difference across it reaches the breakdown voltage VL; then the capacitor discharges completely through the lamp and the lamp ashes briey. For a lamp with breakdown voltage VL = 70.5 V, wired to a 97.1 V ideal battery and a 0.199 mF capacitor, what resistance R is needed for 2 ashes per second
