Circuit Analysis Methods

There are several circuit analysis methods. In this article I will discuss the most common. In the proceeding discussion I

There are some important parameters to consider on how to select a fuse. These are the Current Rating, Ampere Square

In this article I will discuss Fuse Operation and Principle. A fuse is a simple electrical part which consists of

Current transfer ratio is comparable to BJT’s HFE or beta (β). This is the ratio of the optocoupler’s collector current

Way back several years ago, power supply designers and engineers are continuously searching for innovation. Long time ago what is

Relay is made up of two elements; the coil and the contact. The coil needs to be energized so that

Opto coupler CTR explanation is not well elaborated by other authors and before I was also having hard time of

MOSFET is not well discussed in the undergrads; much more how to designing MOSFET switch. MOSFET stands for metal oxide

One of the usual applications of optocoupler is to provide isolation between two ground reference. That is why it is

How to drive a transistor into hard saturation? In using a transistor to operate as a switch you must drive
