In this post I have explained how electret microphone devices work, through appropriate diagrams and formulas. What’s a Microphone A microphone is a device designed for transforming weak sound vibrations into tiny electrical pulses, which can be then amplified through a power amplifier over a loudspeaker for achieving a louder reproduction of the sound. The […]

Clipper and Clamper Circuits Explained
In this post I am going to explain clipper and clamper circuits. The clipper and clamper are called wave shaping circuits because they convert the incoming signal wave to another kind of useful wave. They are used widely in power supplies, filter circuits, RF transmitters / receivers, voltage suppressors, audio amplifiers and the list goes […]
What is Constant Current Source – Facts Explained
In this post I will try to analyze what is constant current source and how it affects a load, or how it may be used with a load correctly for achieving the most efficient results. The following discussion between me and Mr. Girish will clearly explain what is CC or how constant current operates. How […]
Constant Current Generator Circuits Explained
Constant current generators (CCGs), as the name suggests, are circuits designed to produce a steady load current regardless of significant fluctuations in load resistance or voltage levels. Basic Constant Current Generator Circuit Illustrated in Figure 1 is a basic example of such a circuit. In this configuration, Q1 operates in the common emitter mode. A […]
Simple Triac Triggering Circuits Explained
In this post I have explained the fundamental methods of triggering a triac, and also discuss the right way to connect the terminals of a triac. Triacs are solid-state bidirectional thyristors that can switch across both the AC half cycles on a 120-volt or 240-volt Ac power system. A triac could be activated (switched on and […]
How To Calculate and Connect LEDs in Series and Parallel
In this article I have explained how to calculate LEDs in series and parallel using a simple formula and configure your own personalized LED displays, now you don’t just have to wonder how to wire led lights? but actually can do it, know the details here. These lights are known not only for their dazzling […]
