TRANSISTORS: Using a multimeter and checking voltage drop across the base and emitter. My reading was .8volts indicating that there is low voltage being used and high current is still being generated. The voltage drop across the collector and emitter was .o6volts indicating little resistance in the boundary meaning its a good switch and well saturated. In fig13 the area coloured black is where you want your readings to be. low voltage high amps. (it is called the saturated region) The region coloured red is called the cut off region. The cut off region is where the transistor is not working properly. It is using to much voltage and also is not creating good amperage flow. (fully closed). The middle region is the active region where the transistor is working also. I learnt that using a transistor you can switch high current using low current through the base to emitter which then allows high current through from the collector to emitter to flow through.
you need to show your calculations, a picture of the circuit or the wiring diagram. The region marked B is not the active region look again. Also you need to explain what you learnt for doing this experiment
