In this article we study how potentiometers work and try to understand how to connect potentiometers in electronic circuits. How Potentiometers Work Potentiometers, or pots as these are called in short form are passive electronic devices which are basically just variable resistors, or resistors whose values can be altered from zero maximum within the given […]

USB Isolator Diagram and Working
The following email discussions were sent to me by Mr John Sweden who is one of the avid readers of this blog, here he explains about an USB isolator device, and how it may be incorporated while using an oscilloscope with a PC, in order to safeguard the oscilloscope and the test circuit from accidental […]
Sine wave PWM (SPWM) Circuit using Opamp
SPWM refers to Sine Wave Pulse Width Modulation which is a pulse width arrangement in which the pulses are narrower at the start, which gradually get broader at the middle, and then narrower again of the end of the arrangement. This set of pulses when implemented in an inductive application like inverter enables the output […]
How Thyristors (SCR) Work – Tutorial
Basically an SCR ( Silicon Controlled Rectifier) which is also known by the name Thyristor works quite like a transistor. What SCR Stands for The device gets its name (SCR) due to its multi layered semiconductor internal structure which refers to the “silicon” word in the beginning of its name. The second part of the […]
How Mosquito Traps Work
Mosquito and other forms of fly trap mechanisms work by making use of luring techniques for attracting the insects, which involve carbon dioxide gas, body odor simulators and ultraviolet lights. These traps become very useful in areas which may be highly infested with mosquitoes, however due to its high costs such traps are not very […]
What’s PWM, How to Measure it
PWM stands for pulse width modulation which signifies the variable nature of the pulse widths that may be generated from a particular source such as a discrete IC, MCU, or a transistorized circuit. What’s PWM In simple terms a PWM process is nothing but switching ON and OFF a supply voltage at a particular rate […]
