Assuming your reference to "earthing" is grounding (Grounding Electrode Conductor), a pipe is, as it sounds, a pipe (i.e. water pipe). A plate would be, as it sounds, a square (or rectangular) copper plate which would be buried in the ground.

It does. We call this current, or currents, 'eddy currents', and they are minimised by using laminated cores.

Yes you can, in fact I almost guaruntee you did to write the question - the RAM in your computer is likely DRAM, or dynamic random access memory, which uses capacitors to store bits. The problem with using capacitors is there is always some leakage current flow, which results in slowly draining the capacitor's voltage. To prevent the loss of data, DRAM continuously "refreshes" itself by measuring whether the capacitor is charge or not, and fully charging it if it is considered a logical '1'. The capacitor's voltage will again slowly drain off until the next refresh cycle.

The main benefit of this type of memory over more static, gate based memory is it is very cheap, and easy to manufacture.

The answer below this is not correct, a transformer can only be used on AC not DC. So the statement, "A transformer is a device used to increase or decrease DC voltage" is false

The above comment relates to an entry which was obviously deleted.

However, the above comment is also false. The ignition coil in of a petrol engine is a transformer, a pulse transformer. It's d.c. which passes through the primary, not a.c.

A: this is a passive component as opposed to a device that is active answer is yes it does that but more importantly it isolates and match in/out impedance's

In natural frequencies the output of the system will be less than the maximum level. In the resonance frequency the output of the system will be the maximum level.

It's the product of the resistance of that resistive load and the current passing through it.

how am i suposed to answer it if i am asking wat it is

Need to know the wire size of the core conductors.

Salt Generators can run on 110/120 volts or 220/240 volts. They have a transformer that steps the current down to 12 volts so the electrical usage is very minimal. None of the manufactures even mention power usage because it is so low; your pool pump is going to draw 100 times more power than a salt generator. So if you are thinking of installing a salt generator don't even make this a consideration because if it cost you $10 a season I would be shocked (no pun intended).

Surface wiring is wiring that is enclosed in some kind of containment and surface fixed. For example if you installed a conduit containment system to supply a socket this is screwed to the walls with "saddles" and a mounting block is used to protrude the socket off the wall to take the conduit. This is surface wiring as opposed to concealed wiring which is encased in the fabric of the wall and all you see is the socket.

any signal, be it be noise is composed of sinusoids...so when one differentiates sinWt with respect to time it becomes WcosWt ...hence the signal gets multiplied by W..

This is relative to the purpose or application. 1 mega ohm may be considered "low resistance" when testing insulation levels; when testing a cable, 1 ohm may be too much. When testing substation ground grids, I believe 1 ohm is the maximum allowable value in some countries.

A mulit tap ballast is in fact an auto transformer.

One 150 watt inverter reports 0.2 Amps (=approx 2.4watts)

Another inverter (180 watts?) reported 0.4 Amps

If you find a fairly complete spec sheet, it may tell you the Amps or Watts that it uses under "No Load".

I'm the originator of the question, and I discovered the "additional" specs.

Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.

Super capacitor have high capacitance compare to normal capacitor. Super capacitor use two layer of dielectric medium whereas in normal capacitor single medium dielectric.

Because of this super capacitor use as alternate power source for RTC when computer is off.

along the lines of a railgun or coilgun

Arc. It's where electrical resistance is used to create the heat for the welding process.

The man who gave his name to the company and stereo music in a small package to the planet goes by the name of Amar Bose. Apparently he did have help from others but his name is best known through the world of high quality sound

High-voltage transmission line conductors are 'bundled' -that is, each 'line' comprises two or more conductors, rather than a single conductor, suspended from each insulator chain.

The reason for bundling is to reduce the intensity of the electric field on the surface of the conductors (the same field is shared between the surfaces of several, rather than just one, conductors), which would otherwise result in a breakdown of the insulating property of the air immediately surrounding a single conductor.

In the UK, 400-kV transmission lines use a bundle of four conductors per line, and 275-kV transmission lines use a bundle of two.
