Have you ever had a potentiometer whose highest value was some high amount? This will fix that problem.
Parts:
One NPN transistor 
One PNP transistor 
Two resistors (you might need to tweak the value a little)
One load (motor, LED, light, etc.)
One switch
One potentiometer (adjustable resistor)
3V battery
Wire

Can't we do the same with two npn transistors?

Yes, we can. That would be called a Darlington transistor. This one was invented by some other guy, but before I even knew this, I had made one using some Snap Circuits parts.
