A device called an ammeter is used to measure current. Some types of ammeter have a pointer on a dial, but most modern ammeters have a digital display. To measure the current flowing through a ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

The motion of charged particles causes electrical effects, small shocks, lightning and sparks. Electrical fields cause forces to act on charged particles. How to affect electric current - OCR 21st ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

The film explains the fundamentals of electricity, including static and current electricity, the behavior of electrons, and the concept of electrical circuits. It demonstrates how static electricity ...

Flow of electric charge is known as electric current and in electric circuits the charge is carried by moving electrons in a wire. In this article you will get 10 solved Physics practice questions ...

The improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior. The improved circuit is shown below.

Inductors are simple coils of wire, but they play a powerful role in electronics. This video explains how inductors store ...

Ordinary power supply design includes current limiting as a protection feature. In product design, this is usually sufficient in that the engineer decides the loads on the supply by design. However, ...
