Answer by Anton Stafeyev for Simple transistor & capacitor circuit question
To simplify all the answers above.Once capacitor is fully charged it will have high resistance and will not let the current through. So in order to keep it as a short back up power all u need is to...

Answer by Olin Lathrop for Simple transistor & capacitor circuit question
First draw the circuit with positive power at the top negative at bottom, power currents generally flowing down, and signals feeding left to right. If you do that, two useful things happen. First, many...

Answer by Some Hardware Guy for Simple transistor & capacitor circuit question
Try this instead. Use your LED instead of the diode I used and you may need to adjust R8 to get the right amount of current flowing. In this configuration current will flow, remove the endof R7 that's...
