I understand that when we apply voltage to the Base of the PNP Transistor (Emitter, Base, Collector), we actually block current from passing from Emitter to Current.
If there is no voltage applied to base, then current flows freely.
If this is the case... how come when I wire the following:
1.) + terminal of battery to
2.) diode (pointing towards +) to
3.) "Emitter" of PNP Transistor
4.) The "collector" of PNP transistor goes to
5.) - terminal of battery.
I get no closed circuit? (by the way, there's a resistor and LED between 4 and 5). However, when a voltage is applied to the base (even the slightest), the current is open?
