please explain carefully, thank you. I have attached an image.

l7.A simple blinking light circuit is constructed using a neon lamp connected in parallel to a capacitor, as shown in the diagram. When the voltage across the lamp is relatively low, it does not conduct electricity. Therefore, it is effectively not there from an electrical point of view. In this case, current ows through the RC circuit (R 36 k and C 3.0 F) and charges the capacitor from the 110 V power supply. When the voltage across the capacitor reaches 77 V, the neon gas ionizes quickly and the lamp becomes a good conductor, which causes the capacitor to discharge almost instantaneously. The energy stored in the capacitor is given off as a ash of orange light. After the ash, the charging process starts again. a. Determine the ash frequency. b.Draw a graph of the voltage across the capacitor versus time, showing three cycles. 36 k9
