Sitting in the passenger seat of a car, giving continual directions, warnings and corrections—this is the common scenario many drivers encounter on the road. Backseat driving, as the term suggests, refers to the habit of offering unsolicited steering advice from the backseat or passenger seat. It is a widespread behaviour that crosses generations and cultures,…

When accuracy matters, engineers turn to the Kelvin Connection. This technique, sometimes known as the four-wire method, eliminates the resistance of leads and contact interfaces from measurements, delivering results that traditional two-wire methods cannot achieve. In this comprehensive guide, we explore the Kelvin Connection in depth: its principles, how to implement it, the problems it…
