I tried this circuit and was confused about the theory of capacitors.
Here's what I'm supposed to do: on pressing S1, the capacitor is charged and the led blinks for a second. On pressing S2, the capacitor discharges.
When I try to press S1 without discharging the capacitor again, the led doesn't blink. Now capacitors are supposed to allow change in voltages across them i.e. the led should blink when the capacitor is charged, right? Why doesn't it?
