Output Pole
Pole separation is typically not significant enough to approximate the response by a dominant single pole since fast amplifiers have values of R B not very different from r'' b nsequently, the r'' b term in (8.115) cannot be ignored. The value of R B at maximum pole radius occurs when the poles are repeated and ζ = 1. This results in a fourth-degree equation

6 FAQs about [Special topic on single-pole capacitors]
What is a power capacitor?
A capacitor is a device that stores energy within an electric field. This is achieved by having two oppositely charged electrical conductors separated by dielectric materials. Power capacitors are constructed of several smaller capacitors, commonly referred to as “elements”, “windings” or “packs”.
What are the benefits of power capacitors?
The incorporation of capacitors into a power distribution system offers economical and operational benefits, including increasing system load capacity, reducing losses and improving power factor. What are the different types of power capacitor units?
What is a capacitor used for?
Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with resistors, filtering out unwanted frequency signals, forming resonant circuits and making frequency-dependent and independent voltage dividers when combined with resistors.
What are the different types of power capacitor units?
There are two primary classifications of power capacitor units: Internally fused units consist of elements that are each protected by a series connected fuse inside the capacitor enclosure. As an element fails, the internal fuse protecting that element clears.
What are power capacitors made of?
Power capacitors are constructed of several smaller capacitors, commonly referred to as “elements”, “windings” or “packs”. These elements are formed from multiple layers of aluminium foil (conductors) and polypropylene film (dielectric) wound together. When interconnected, multiple elements combine to function as a single capacitor unit.
