For Higher Physics, learn the key features of characteristic graphs for capacitors. Use graphs to determine charge, voltage and energy for capacitors.
The Dark Side of Capacitors: What Happens When They Fail?
When a capacitor fails, it can have a ripple effect throughout the entire circuit, leading to a range of consequences, including: Power Disturbances And Shutdowns. A failed capacitor can cause power disturbances, such as voltage drops, sags, or spikes, which can lead to equipment shutdowns, data loss, or even safety hazards.

Some capacitors look tube-like due to metal foil plates that roll up into a cylinder. Dielectric material typically sits between the metal foil plates and the cylinder. Then there are capacitors used for commercial purposes which are made from
UK Vintage Radio Repair and Restoration
In some early radios, the troublesome capacitors are contained in shiny card tubes sealed with pitch at each end. I have found it possible to melt out the pitch with a soldering iron and pull the old guts out of the tube with a pair of pliers. When melting out the pitch, let it

CHAPTER 5 CAPACITORS
A typical inexpensive capacitor seen inside a radio is nothing much more than two strips of metal foil separated by a strip of plastic or even paper, rolled up into a cylinder much like a Swiss roll.

Foil vs electrolytic capacitors for tube amplifier power
I found Apex Jr on the auction site has cheap 75uf 600v poly caps for like $5 each that work really well. If you use a tube rectifier you need sub 50uf cap right after the tube. Foil vs electrolytic capacitors for tube amplifier

I swapped in what should have been (from specs, the data sheet and from later measuring the impedance curves), an identical Wima 30uf film cap in place of a Solen film "fast cap" as the first cap in a tube rectifier power supply.
Is a conductor like a capacitor
Sounds a daft question but I got thinking about another question and this cropped-up. Background - In a conductor electrons move seemingly in a random fashion and more so when the conductor is warmer. When a voltage is applied there is a general tendency for electrons at one end of the conductor to start pushing electrons out at the other end i.e. there is a current flow.
Introduction to Ceramic Capacitors | doEEEt
So-called tube capacitors are extruded out of a nozzle and are covered with an electrode paste on the inside and the outside before it''s sintered to its definite material structure. In the same way, the Single Layer Ceramic Capacitor (SLCC) consists of one dielectric layer.
Capacitor Resistance: What It Is and Why It
Initial State: When the circuit is first connected to the voltage source, the capacitor acts like a short circuit, allowing a large initial current to flow. Steady State: As the

6 FAQs about [Tube-like objects appear in capacitors]
What is a capacitor in physics?
What is a capacitor? Capacitors are devices which store electrical energy in the form of an electric field. The process is quite similar to the way mechanical springs store energy in the form of elastic material deformation, to the extent that the math describing both is quite similar, save for the variables used.
What is an example of a capacitor?
Some of such examples are listed below: 1. Camera Flash Camera flash forms one of the most prominent examples of the applications that make use of capacitors in real life. A camera typically requires an enormous amount of energy in a short time duration to produce a flash that is bright and vibrant as desired by the user.
What are film capacitors based on?
Film capacitors based on metal film electrodes have the advantage of being able to self-heal; the electrode material near a localized fault in the dielectric is thin enough to be vaporized by the leakage current caused by the fault, thus eliminating (or “clearing”) it at a cost of some lost capacitance.
What makes a capacitor different?
Capacitors are distinguished by the materials used in their construction, and to some extent by their operating mechanism. “Ceramic” capacitors for example use ceramic materials as a dielectric; “aluminum electrolytic” capacitors are formed using aluminum electrodes and an electrolyte solution, etc.
What are the applications of capacitors?

What is a trimmer & variable capacitor?
Trimmer and variable capacitors are generally used for tuning & matching applications in RF circuits. Radio receivers that indicate the selected tuning frequency by sweeping a mechanical indicator past a scale (or vice-versa) typically have a mechanical linkage between the indicator and the variable capacitor (s) used in the tuning circuit.
