How does a transistor work as a switch and amplifier??


Quote by Drakkith View Post
Do you have a good grasp of basic electronics? Do you understand what voltage and current are? It would greatly help if we understood your knowledge level. Have you taken any electronics classes before?
This is highly relevant. It is no good trying to run before you can walk. To understand how an amplifying device / component amplifies, you must first be really comfortable with what current, volts and resistance are and the mathematical relationships between them.
