I'm attempting to build a simple electronic firework lighter by frying a 10 ohm resistor with a newly purchased 12 volt A23 battery, which is initiated via a toggle switch. I have seen on youtube that the resistors ignite in less than a second, and I expected the same results. Upon closing the circuit (without using the switch), the resistor simply heats up and does not smoke nor ignite. When I tried the same thing using a 9 volt battery, the resistor quickly began to smoke, but did not ignite as I need it to. I tested the A23's voltage, and it was approximetly 11.5 V. My question is why will it not ignite, and how can I correct this.
