My components are
- 2x 1.5 V batteries
- 25V 2200uF capacitor
- 3v Led
- copper cables
My circuit looks like the following.
My understanding here is that as the two batteries are in linked in series, we now have 3v for our circuit.
When completing the circuit the LED starts bright then slowly fades and fades until there is no light at all. Also interestingly if I dissconnect the batteries, wait a minute, and reconnect them completing the circuit, the LED stays off - It does not start bright and fade again.
What is actually happening here? Is the capacitor consuming all the power? If I left this circuit complete for a while, would the capacitor gradually consume all the power until it reaches its 25V and then suddenly release 25V instantly? (blowing the LED of course)
I actually ran this test because I wanted to try to fill the capacitor up, and then dissconect the batteries hopeing to see the LED stay alight for a while running from the capacitors consumed power.(if this is even possible, perhaps my understanding is not correct)
