Hi Guys,
I'm new at Electronics
Since "the working" of capacitators i started experimenting with them in the hope it would become more clear to me. In fact i get's more mysterius every second.
In the circuit in Picture A (picture included) i connected a 390uf capacitator (elco) in series with a red Led (voltage drop +-1.8) . As expected when i turn on the voltage , the led flashes for a second while the capacitator is charging:
Remarks :
1) In this case the LED is not gradually dimming ... it just flashes on and of --> is this normal ?
2) in the case i put attach the crocodile clamps (source voltage is 4V, as shown in circuit A) my capacitator only charges up to a MAX of 2.5 V and across the LED i have a voltage of 1.3V --> I tought that the capacitator charges up to the same voltage as voltage source, in this case 4 V --> Does anyone knows the reason while it only charges partially ?
3) In the case i attach the crocodile clamps directly to the + and - pole of the capacitator (Shown in picture circuit B) , the capacitator does charge up to full 4 V ????
If the capacitator is charged (2.5V or 4V) and i remove the battery clamps and replace them by a wire , should't my LED be flashing for a fraction of a second ??? --> discharging capicator ???? Thi doesn't work either ..; the only way to discharge the capacitator (according to my test) is putting a wire directly from + pole to the - pole of the capacitator.
Thx in advance for the help
Regards,
Mike
