In most countries around the world, we see that the banknote of the highest denomination bears the face of the most respected figure in the country’s history. In the United States of America, that person is Benjamin Franklin whose face dons the famous $100 bill. This article focuses on the Franklin lightning rod, arguably one of Benjamin Franklin’s greatest achievements, through the scientific and engineering perspective in search of the future of lightning protection technology in the rapidly changing world.

In this article, we will discuss the fundamentals of bonding and grounding. To start, we should get an understanding of the difference between bonding...

What Is Earthing & Why and How Do We Connect to...

The thin layer of material which covers our planet—rock, clay, chalk or whatever—is what we in the world of electricity refer to as earth. So, why do we need to connect anything to it? After all, it is not as if earth is a good conductor. It might be wise at this stage to investigate potential difference (PD). A PD is exactly what it says it is: a difference in potential (volts). In this way, two conductors having PDs of, say, 20 and 26 V have a PD between them of 26 and 20 V. The original PDs (i.e., 20 and 26 V) are the PDs between 20 V and 0 V and 26 V and 0 V.
