Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

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 ...

The size of a capacitor affects how much charge it can store (its capacitance), its voltage rating, and its physical ...

The gradient of this graph is equal to the capacitance of the capacitor. \(C= \frac{Q}{V}\) And the area under the graph is the energy stored by the capacitor.

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

New capacitors covering the 5-µF to 60-µF range have been added to the EPCOS line of 4-pin link circuit capacitors operating on voltages from 250 Vdc (180 Vac) to 850 Vdc (350 Vac). The capacitors are ...

Matching several capacitors, without needing a really precise value, can be accomplished with a "high-tech" laboratory capacitance meter. But this is cumbersome and overkill, and not everyone has one.

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

Q. What is the minimum ampacity and minimum size conductor required for a circuit that connects a capacitor to the terminals of a 25 hp, 460VAC, 3-phase, air conditioner induction motor? The rated ...

One of the last remaining unshrinkable obstacles blocking the progress of fully integrated, wearable technology is the clunky component that absorbs and disburses stray electricity and converts ...
