Traditional large-scale power generators ensure a stable frequency of alternating current in the European power grid. Now, researchers from ETH Zurich have found a solution so that wind and solar ...

We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or Alternating Currents). We’ve talked about how they change voltage, which helps transmit electricity ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

A fluorescent starter works because the current heats up a gas discharge tube which causes a bit of metal to bend and touch another, closing the circuit.

Alternating current differs from direct current in several ways. Find out more here.

A research team led by Prof. Tian-Bao Ma from the Department of Mechanical Engineering at Tsinghua University has proposed a ...

There are two types of electrical current: direct and alternating. Each one has unique benefits and disadvantages. Batteries, whether they’re small enough to power your smartwatch or big enough ...

Alternating current (AC) and direct current (DC) are two types of electrical output. With alternating current, the flow of electrons in a circuit alternates between the positive and negative poles ...

Almost everything we use runs on direct current, so why are our houses still wired for alternating current?
