For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.

Use this fun, interactive activity to talk about how conductive materials allow electricity to flow freely, while insulating materials make it slow down or stop. This experiment was developed by ...

In this DIY tutorial, learn how to make your very own USB electric lighter at home with simple materials and step-by-step ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...
