Ever wondered how electrical engineers decide the perfect size of a cable?
In this video, we uncover the hidden mathematics and economic secrets behind single-core cable design.
You’ll learn how the famous constant ‘e = 2.718’ surprisingly plays a key role in determining the most economical diameter of a cable!
We’ll explore stress distribution, voltage relations, and practical examples — step by step — to make this technical concept clear, logical, and fun to learn.
Watch till the end for two real-world calculation examples, and don’t forget to drop your answers in the comments!
