I'm trying to make On-delay circuit with passive components, I use 3 identical AAA alkaline batteries (4.5 v) and use PNP 2N2907 Bjt with 600mA Collector Current to heat(glow) up a small resistor wire
I use a 1000 uF capacitor and 20k Pot resistor for adjustable RC delay, Also I use 6.1v Zener diode however, when I press push button in my circuit the heating element does not even warm-up
following is my schematic
my question is:
Is Bjt not powerful enough to deliver current and heat up the element,
or is my schematic wrong and I should select another component?
if the current is not enough how can I add a wire coil inductor to charge on delay and push more current to the heating element?
updated schematic base on new comments
