Transistor Switching

Statement of purpose
To control current flow with a transistor switch.

Procedure

Using a switch to turn on a LED with a transistor.

Finger-tip transistor switching

Data
Too see a precise understanding of how a transistor works. We adjust the resistance of the potentiometer to control the voltage that is sent to the base.

This is the current emitted by the transistor.

Conclusion

Controlling electricity by a transistor is "expensive", so it is noteworthy that to know that a transistor takes at least .25A at the base just to switch the flow of electricity.
