I'm using DC adapter 5.8 volt with 580 miliamp to produce 1.5 amp by using a pair of NPN transistor 2N3904 to be build as Darlington circuite.
Is it possible?
Hey, I've been asked a question 'what are operational systems on Transistor H-bridge system for a conveyor motor with speed control property's'. I know that system I've put below would work for a lower voltage application, I just cant seem to find any information on high voltage applications. I...
I'm trying to work with IRF640 FET transistor (picture attached). FET transistor picture
The problem is when I put 11V on the G-S voltage. The D-S voltage is 4-6 volts or more.
Why the transistor doesn't open fully?
What am I missing?
In the simulator, the voltage falls to 120.18mV.(as...
As the title says, I was called by a company that fix aeroplane parts, they have a machine that is used for testing generators, it's stopped working and I was asked to have a look. I've told them it's way out of my depth and I pretty much don't have a clue, but said I would stop by and get a...

A transistor is set up in a test circuit and a base current of 12μA is measured. At the same time, the collector current is measured and found to be 2.28mA. The current gain for the transistor under these conditions would be:
(A) 9
(B) 19
(C) 190
(D) 1900
(E) None of the above values...

Could you tell me how you get the answer?
