Hi, I am new to electronics and I am stuck on my circuit.
I have a 6 volt, 4 mA motor that I am running when a 3 volt timer comes on. I am using a TIP120 Mosfet to close the circuit when the timer comes on. I have another 6 volt, 4mA circuit that I want to open when the 3 volt timer comes on. I am trying to use a JFet to accomplish this. I don't know how to calculate what size JFet that I need. Thanks for any help you can give me.
