Our last go-round inside a DC circuit! We’ll encounter junctions, loops, and capacitors! What happens when there are MULTIPLE batteries, connected in ‘parallel’? And what happens when we add ...

How do those defibrillators you see on TV actually work? Surprise! Physics can explain! So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, ...

Ferroelectric materials, which were discovered nearly a hundred years ago, and have led to a huge range of applications, including digital information storage and neuromorphic computing, are still not ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

The electron transport properties of graphene devices are critical to many applications, but our understanding of these properties is still incomplete, in spite of rapid advances in recent years. One ...

The new capacitor is much smaller than a conventional device. (Courtesy: Nanyang Technological University) Researchers in Singapore have developed a prototype polymer capacitor that can store much ...
