Build a simplified ignition module
Find the maximum current value of the transistor from the data sheet, the resistance of the coil. Then calculate the resistor need to protect the circuit.
14V , 100mA
14/0.100 = 140 ohms
Connect your circuit up to the function generator and fire the spark plug.
What difficulties did you encounter in building this circuit?
The resistor prevented our circuit from working because the resistor was drawing too much current.
If you were going to build this circuit again what would you do differently?
I will not involve the resistor.
you were meant to get this working!
