Figure 1-11. - Transistor operation.
the makeup of this transistor is two elements of N-type material (collector and emitter) with an element of P-type material (base) sandwiched in between. The NPN transistor will allow a high current negative charge to flow from the collector to the emitter whenever a relatively low current positive charge is applied to the base.
Q 1 . What material allows electric current to flow?
Q2. Name two electrical components that use semiconductors?
Q3. What is the basic difference in operation between a diode and a transistor?Continue Reading
