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 […]
How to Connect Transistors (BJT) and MOSFET with Arduino
The interfacing of power devices like BJTs, and MOSFETs with Arduino output is a crucial configuration which allows switching high power loads through low power outputs of an Arduino. In this article we elaborately discuss the correct methods of using or connecting transistors like BJTs and mosfets with any microcontroller or an Arduino. Such stages […]
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 […]
Load-Line Analysis in BJT Circuits
So far we have been studying BJT analysis dependent on the level of β over their corresponding operating points (Q-point). In this discussion we will check out how a given circuit conditions can help in determining the possible range of operating points or Q-points and in establishing the actual Q-point. What is Load Line Analysis […]
