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?

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