The LED and capacitor are in parallel. Therefore the LED cannot light until the capacitor charges to at least the LED's forward voltage. This doesn't really address the problem. The voltage source determines the voltage, so the capacitor can not have any other voltage than 2.7.
As the capacitor gets charged, the voltage accross it augments, until the battery cannot push more electrons. At this point the capacitor voltage has equalized the battery voltage. No more electrons flow, the bulb finally turns off. To release the energy stored in the capacitor, remove the battery from the circuit and connect the wires together.
One is parallel to "DO LED" No it isn't. One is parallel to "DO LED" No there isn't. the 100nF on the left is for supply decoupling (also called a bypass capacitor). The 100 nF cap in parallel with the photo transistor is to filter out any noise from the photo transistor.
The capacitor and the LED are in parallel, so the voltage across the capacitor is the voltage across the LED. If the capacitor is discharged, the voltage across it is zero, so the LED cannot light. @BorisCerar The LED cannot light until the voltage across it equals or exceeds its forward voltage. The LED and capacitor are in parallel.
You must apply a threshold voltage across it before it starts to conduct. As such, when power is first applied the voltage across the capacitor and LED is zero. The capacitor is setting the voltage across the LED. After that, the LED can not start to turn on until the voltage across the capacitor reaches the LED's threshold voltage.

Short answer: Current stops when the capacitor gets charged up to the battery voltage. When current flows through the circuit, the bulb lights up. In this case you can consider the bulb as a ''current detector''. Current in this case is flow of charge, and the charge carriers are electrons. They are pushed around because the battery pushes them ...

If light bulbs are attached in parallel, the current will be divided across all of them. But if the light bulbs are connected in series, the current will be the same in all of them. Then it looks like the bulbs should be brighter when connected in series, but actually, they are brighter when connected in parallel. Why is that?
Several capacitors may be connected together in a variety of applications. Multiple connections of capacitors act like a single equivalent capacitor. The total capacitance of this equivalent single capacitor depends both on the individual capacitors and how they are connected. There are two simple and common types of connections, called series and parallel, for which we can easily …

This proves that capacitance is lower when capacitors are connected in series. Now place the capacitors in parallel. Take the multimeter probes and place one end on the positive side and one end on the negative. You should now read 2µF, or double the value, because capacitors in parallel add together. This is a practical, real-life test you ...

Since the capacitors are connected in parallel, they all have the same voltage V across their plates. However, each capacitor in the parallel network may store a different charge. To find the equivalent capacitance (C_p) of the parallel network, we note that the total charge Q stored by the network is the sum of all the individual charges:
The capacitor that is parallel to the photo-transistor is used to extend the time the DO_LED is on after the flame has disappeared or momentarily ceased. The recharging of that capacitor (100 nF) is via the 10 kohm resistor hence the CR time is 1 millisecond.

When capacitors are connected together in parallel the total or equivalent capacitance, C T in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C 1 is connected to the top plate of C 2 which is connected to the top plate of C 3 and so on.
For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.
In a series circuit, all of the components are arranged on the same path around the loop, and in the same way, series capacitors are connected one after another on a single path around the circuit. The total capacitance for a number of capacitors in series can be expressed as the capacitance from a single equivalent capacitor.
