- Nominal 25V on the capacitor means it can tolerant up to 25V input I think. What happen to the capacitor is that it store the electricity, not consume, until it is charged up to 3V in the opposite direction to the batteries, meaning that the longer tail of the capacitor becomes 3V. So then the voltage drop between the LED gradually(the speed depends on the capacitance of the capacitor) becomes 0V and the LED.
- When you remove the batteries and INSTANTLY connect the LED with the LED on the other side, the capacitor might source current for a little while, but the electricity stored in the capacitor might be too small to source enough current to LED you
can notice on eyes. Remember, the voltage itself does not tell how much
current the device can source and light up the LED. - Please connect resistors BTW.
