It demonstrates how static electricity is created and how current electricity flows through complete circuits, using examples like a train and various experiments.

Circuit breakers are a safety feature that automatically interrupts the flow of electricity in the face of a system fault or ...

Circuits that supply current (using positive current flow convention) are usually known as a current source and one that limits the current flow on the ground side is known as a sink.

In a parallel circuit, if a lamp breaks or a component is disconnected, the other components continue working. This is because current continues to flow along remaining paths in the circuit.

Follow the current Remember that we call a collection of connected electrical or electronic components a “circuit” because currents always flow from a source to a load and then back via a return ...

As the current flows through the PTC thermistor, it will quickly heat up and its resistance will quickly increase to a point where the current flow will dramatically reduce, essentially removing the ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current … ...

Most common current-limiting implementations have a voltage drop that’s too high for today's systems with their low-voltage supply rails; this design with its far lower voltage drop is a better fit.

Despite their designed current-handling capacity, such circuits still need current limiters and circuit breakers to protect them from fault conditions.

The main goal of this research group is to develop systems capable of controlling heat flow in nano- and microstructures as efficiently as electrical circuits handle current.
