Hi all I want to use a transistor has a switch but having a bit of a problem working out the resistance value.
I will be using a reed switch to do the triggering Im working on 24 volts. I would like to use a 2n3055 or a Tip3055 now the load is at the max 4 amp. The in put out put voltage from the reed switch is 24v so I need a resistor to go between the reed switch and the bass of the transistor. Can any one help please.
Im also looking for the same but on 12v same 4 amps
Any help will be appreciated.
I have looked at all the equations and illustrations on the net but its just got me even more confused.
So if its possible can anyone pleeeeeeease post some thing like, you will need a 680 ohms resistor?
Many thanks.
