If I have a capacitor + attached to transister "in" + will the transister then "trigger"?
I know that a transistor is current controlled, so will it start only by a capacitor or will I need a resistor in between to draw some current? Cause a capacitor itself shouldnt draw any current.... I think.
My project is to charge a capacitor to "trigger" the transistor for some time. The transistor will then open for current and turn on a 12v relay.
