Long Duration Timer Circuit using IC 4541: Working and Calculations

Last Updated on June 14, 2026 by Swagatam 2 Comments

The CD4541B is a CMOS programmable timer IC, and we use it where long delay interval is needed for a load, and also for jobs like frequency division, or timing pulse work. And all this happens with only just a few outside parts, not much around it. With ordinary IC 555, when delay becomes too […]

Understanding Triac Snubber Network Calculations

Last Updated on May 20, 2026 by Swagatam 2 Comments

controlling inductive load with triac

You may find electronic circuits that frequently utilize triacs to manage mains powered loads. However, these setups commonly feature an inconspicuous capacitor and resistor combination across the triac – a snubber network. The functions of these components are more intricate than they seem. Exploring snubbers and grasping basic triac theory is valuable. Triac Operation A […]

Wheatstone Bridge Circuits Explained with Calculations

Last Updated on June 8, 2026 by Swagatam 11 Comments

Table3

A Wheatstone Bridge circuit is commonly used to measure resistance, inductance, capacitance, and impedance. These are made up of four parts or arms that are joined in series in a diamond like bridge configuration. These four arms carry the individual components such as resistor, inductor or capacitor connected across the fur junctions. An alternating current (AC) or […]

zener characteristics

Zener diodes – named after its inventor Dr. Carl Zener are fundamentally used in electronic circuits for generating precise voltage references. These are devices that are able to create a practically constant voltage across them regardless of variations in circuit and voltage situations. Externally, you may find zener diodes a lot similar to standard diodes […]
