In many sensitive electronic circuits or loads, adjusting the current limit in its power supply could be one of the most crucial requirements for ensuring a fail proof safety for the various vulnerable devices. A simple method of sensing current this using resistors has been discussed in this article. Integrating a Current Sensor Stage The […]

Difference Between Alternating Current(AC) and Direct Current(DC)
In this post we try to investigate the mains differences between alternating current (AC) and direct current (DC). The word AC and DC are pretty common with electronics and we all come across it while developing or dealing electronic circuit designs. Overview Though the terms are very ordinary with the field, many noobs become confused […]
Difference Between Current and Voltage – What is Voltage, What is Current
The following data explains the important aspects connected with the electrical parameters like voltage and current, the content also explains in simple words how to differentiate the two parameters. What is Current It is the number of electrons flowing at any instant through a conductor or across the positive and the negative of a conductor […]
Transistor Zener Diode Circuit for Handling High Current Stabilization
The high power “zener diode” circuit using transistor shunt regulator presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. Normal Zener Limitation The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot […]
High Current Zener Diode Datasheet, Application Circuit
Zener diodes that are normally available are mostly 1/4 watt or 1/2 watt types. And it is quite valid since the basic function of zener is to create stabilized reference voltage. Zener diodes are not designed for current regulation directly. However, for some applications where shunting excess voltage and current is necessary a high current […]
INA219 Current Sensor Circuit Diagram and Datasheet
In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]
