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 ...

Electric circuits often consist of several elements, some combined in series and others in parallel. The methods used to analyze series and parallel circuits can be combined to analyze these ...

LEDs are finding their way into more products than ever before. Automotive lighting, TV backlights and tablets are just a few applications that require multiple LEDs. Driving a large number of LEDs ...

Previous tutorials have described that resistors may either be connected as a series circuit or a parallel circuit where the currents and voltages are obtained using Ohm’s Law. To produce more complex ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, taking the form of conductive plates separated by an insulating material ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

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, ...

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 ...
