This pressure difference causes water to flow around the loop – just like the potential difference produced by a cell or battery causes electrical current to flow in a circuit.

Potential difference in series circuits Try the experiment online Resistors in series Test your knowledge Resistance ® close resistance (R)How difficult it is for current to flow. increases when ...

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.

Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance to changes in pipe volume.

Since the current that flows during a fault is almost 90∞ out of phase with the system voltage, series reactors can be used to limit short circuit current. Current-limiting reactors can provide a cost ...

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

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.
