While teaching about transistors, mrs.. kwon shows a video of a hand pump being used to draw water from a well. she points out how the person primes the pump by pouring a smal amount of water into it before the water would start to flow. what does the water used to prime the pump represent? a. the current in the emitter that amplifies the signal b. the current in the base that amplifies the signal c. the current in the collector that turns the transistors on d. the current in the base that turns the transistors on

d. the current in the base that turns the transistors on.

While using Transistor as switch, in the switch off state the current in base is 0. To switch on the transistor, a current at base is required that allows the flow of current through the transistor like a small amount of water is poured to prime the pump. The current won't flow through the transistor unless the biasing of base allows the current.

the inner core.

good luck: )

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
