When considering capacitors during operation, equivalent series resistance (ESR) is the real part of the impedance and represents losses for the capacitor in the equivalent circuit.

Our last go-round inside a DC circuit! We’ll encounter junctions, loops, and capacitors!

One of the most overlooked, but important performance characteristics of a capacitor used in power circuits is its equivalent series resistance.

What happens when you connect a charged capacitor to an inductor? You get an oscillating circuit. Here's how it all works.

Figure 1 The theoretical capacitor is a simple reactive element, but a real one has equivalent series resistance due to ohmic series resistance, leakage resistance, and dielectric loss. (Image ...

While that concludes our history of the capacitor, there’s plenty more we’re sure could be added based on the large number of types of capacitors alone.

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct… ...

In this course, you will learn the purpose of each component in an equivalent-circuit model of a lithium-ion battery cell, how to determine their parameter values from lab-test data, and how to use ...

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the ...

In a circuit, capacitors help to steady the flow of electrical current — absorbing surges and providing temporary power when necessary — but their size has been a limiting factor in the development of ...
