Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering ...

When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular ...

A simple electrical simulation of this circuit produced 240Vppk across the transducer, which is more than double that created in the real circuit. Acoustic loading may represent the majority of losses ...

Figure 1: Simple threshold circuit – which does not work with some references! When I designed this circuit I assumed that if I used 1MΩ as R fb the current (approx 10μA) flowing into the reference ...

Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the ...

The topic of electricity often poses difficulties for many secondary school students in physics lessons. Researchers have now developed and empirically evaluated a new, intuitive curriculum as ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic circuits.
