A BJT common collector amplifier is a circuit in which the collector and the base of the BJT share a common input supply, hence the name common collector. In our previous articles we have learned the other two transistor configurations, namely the common-base and the common-emitter. In this article I have explained the third and […]

Cathode Ray Oscilloscopes – Working and Operational Details
In this post I will elaborately explain how Cathode Ray Oscilloscopes (CRO) work and its internal construction. We will also learn how to use a CRO using the various controls and understand the graphical representations of the various input signals on the display screen of the scope. Importance of Cathode Ray Oscilloscopes (CRO) We know that majority […]
Capacitor Inductor Calculations
Inductors can be imagined as the opposite of capacitors. The main difference between a capacitor and an inductor is that a capacitor carries a protective dielectric between its plates, which inhibits the conduction of current across its terminals. Here it acts like an open circuit. On the other hand the inductance of an inductor is […]
Learning Basics of Semiconductors
In this post I will comprehensively explain regarding the fundamental working principles of semiconductor devices, and how the internal structure of semiconductors function under the influence of electricity. The resistivity value between these semiconductor materials neither has a complete conductor characteristic nor a complete insulator, it is in between these two limits. This feature may […]
How to Troubleshoot Transistor (BJT) Circuits Correctly
Troubleshooting BJT circuits is basically a process of identifying the electrical faults in the network using multimeters across the various nodes in the circuit. BJT troubleshooting techniques is a huge topic and therefore including 100 % solutions and strategies can be perhaps difficult within a single article. Basically, the user should know about a handful […]
DC Biasing in Transistors – BJTs
In simple terms, biasing in BJTs may be defined as a process in which a BJT is activated or switched ON by applying a smaller magnitude of DC is across its base/emitter terminals so that its is able to conduct a relatively larger magnitude of DC across its collector emitter terminals. The working of a […]
