Phototransistor : Construction, Circuit Diagram & Its Applications
A phototransistor is nothing but an ordinary bi-polar transistor in which the base region is exposed to illumination. It is available in both the P-N-P and N-P-N types having different configurations like common emitter, common collector, and common base but generally, common emitter configuration is used. It can also work while the base is

What is NPN Transistor? - Definition, Construction & Working - Circuit
Definition: The transistor in which one p-type material is placed between two n-type materials is known as NPN transistor NPN transistor amplifies the weak signal enter into the base and produces strong amplify signals at the collector end. In NPN transistor, the direction of movement of an electron is from the emitter to collector region due to which the current
Common collector - Wikipedia
In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer. In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both (for example, it may be tied to ground
LDR Circuit Diagram - Build Electronic Circuits
Nov 01, 2013How The LDR Circuit Diagram Works. The LDR circuit diagram works like this: When it’s dark, the LDR has high resistance. This makes the voltage at the base of the transistor too low to turn the transistor ON. Therefore, no current
Common emitter configuration of BJT - Electrical Classroom
Operation of common emitter amplier. The common emitter amplifier circuit comprises of a voltage divider bias and coupling capacitor C B and C C at the input and output and a bypass capacitor C E which is connected from the emitter to the ground. The capacitor C B couples the input signal to the input port of the amplifier. It also separates the AC signals from the DC
