To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in series. If one lamp breaks, the other lamp will not light. The current is ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, ...

Fig. 1 As I wrote in the Jan. 1 issue of Radio World, a German physicist named Georg Ohm published a paper in 1827 that described the interaction between voltage ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...
