I have been asked to demonstrate some electrical things to a GCSE student. One of the things on the syllabus is potential difference, and another is EMF – electromotive force. I had always assumed ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...

Forbes contributors publish independent expert analyses and insights. Understanding the difference between what someone does now (performance) and what they could do in the future (potential) is ...

When ‘potential’ is seen as crucial to moving up the career ladder, women seem to lose out. Why? In her 2013 book Lean In, Facebook COO Sheryl Sandberg claimed that most men would apply for positions ...

This equation can be used to calculate what the output might be from a particular transformer, or to work out how to design a transformer to make a particular potential difference change: ...

This article focuses on single-cell electrophysiology and introduces the fundamentals of electrophysiological investigation by describing the ionic basis of action potentials and the different ...
