Am I using these MOSFETs correctly?
I am designing and testing a circuit that charges a capacitor to around 50V using a boost converter when 'ARM' is high, then discharges it through a solenoid when 'FIRE' is high. ARM and FIRE are ...

How do I select a transistor base's parameters for controlling a solenoid?
I have a small solenoid which is to be powered by a DC power supply. Current is 5A. Resistance is 3.5 ohms.
I only want this solenoid to be on for around 20 ms, so I figured a transistor was the best ...
