While teaching about transistors, Mr. Mendoza shows a video of a hand pump being used to draw water from a well. He points out how the person primes the pump by pouring a small amount of water into it before the water would start to flow. No matter how much water is used to prime the pump, once started, the pump provides a steady flow of water while the handle is operated.

What is Mr. Mendoza using the hand pump to model?

its use as a switch to make a small signal into a large signal
its use as an amplifier to make a small signal into a large signal
its use as a switch to turn on a large current using a small current
its use as an amplifier to turn on a large current using a small current

Mr. Mendoza is using the hand pump to model the transistor's use as a switch to turn on a large current using a small current.  

If my teacher had used this model (around 1972) to illustrate the concept, I don't think I would have absorbed the idea.  I was substantially clueless, and the model is pretty abstruse.

Answer:

C. its use as a switch to turn on a large current using a small current
