Do step up-down transformers waste electricity when plugged-in but not in use - note this is not referring to AC-DC converters but transformers that change voltage between 110-120v to 220-240v?

yes -- the input current still runs in the primary coil.

What effect does pencil lead have on the flow of electricity and on a motor and speed of the motor?
If the question is asked correctly and if graphite conducts electricity (I don't know if it does) then any pencil lead on a conductor would infinitesimally decrease the resistance of the circuit, too small to matter. Metal shavings and other debris that conduct electricity are very dangerous because very often it falls into places where you do not want current to flow. If you are referring to "penciling" the insulation on a conductor then please restate the question and I will be happy to answer it for you.
What is the difference between size and shape of an object?
When referring to size, something can be very small or very big. When referring to the shape, an item can be round, square, or even a triangle.
What is the difference between MWe and MW in electricity?
MU is Amount of Energy uswed while Watts is amount of power delivered.1 U = 1KW HR that is 1 unit is amount of power consumed by 1 KW Bulb when on for 1 Hr.1MU= 1MKWhr=1BWHr

The purpose of transformer percentage impedance?
Inherently, the actual impedance seen at the secondary voltage will be different than that seen at the primary voltage. To make things easy, we use symmetrical components, where transformers are reduced to a p.u. (per unit) impedance. 100 x p.u. is equivalent to the percentage impedance you are referring to. When converted to per unit, a transformer has one impedance, not two, so it does not matter whether you are looking through the transformer from the secondary or the primary.
Where is Buchholz from?
If you are referring to a Buchholtz relay used to protect transformers, then it was named in honour of its inventor, Max Buchholtz, an engineer with the Prussian Electricity Supply Company, in Kassel, Germany.
Where can I find online information about Cadillac converters?
You are probably referring to catalytic converters. These are mechanisms that turn harmful gases and other particles into nitrogen gas. The correct spelling will lead to you a variety of helpful websites.
When referring to electricity the acronym AC stands for?
Alternating Current.
Does and insulator emit electricity?
'Electricity' is not a quantity, it's a topic. So 'emitting electricity' is quite meaningless. You need to rephrase the question to specify what quantity you are actually referring to when you say 'electricity'.
Small units of electricity?
As 'electricity' is not a quantity and, therefore, cannot be measured, you will need to be more specific as to what you are asking. For example, are you referring to current, voltage, etc?
How do you spell electicty?
The adjective form is spelled electric (referring to electricity, or other energetic form).Other associated words:electrifiedelectrifyelectronelectronic
Is there a Saturn in transformers?
As far as I am aware, their universe is EXACTLY the same one we live in. If we have Saturn, so do they. There's just nothing interesting on it... yet. Referring to the vehicle, no. Transformers are based off of Chevy vehicles. Also, there were no Saturns when the toys first went into production, and it went out of business before the movies.

if your referring to making a copy of your music whether to a cd, computer, cassette, etc... NO it is not legal !! look up the first sale doctrine.... you may dispose of it how you like... but you may not reproduce !
Is matter a good or bad conductor of electricity?
That depends on what type of matter to which you are referring to. Things such as metal or water are excellent conductors. On the other hand, rubber and other such materials are very poor in conducting electricity.
Why are conductors important?
Orchestra conductors are important because they keep all the musician in sync and on time with each other. If you're referring to conductors of electricity, they're important because they let electricity flow.
How do you defeat mix master in transformers dark of the moon for PS3?
If you are referring to when he is attacking ratchet you simply wait till he attacks you and take out the gears on the floor with your heavy iron. If you are referring to when he attacks you in the junkyard you simply keep shooting his shields with the upgraded heavy iron sent to you by wheel-jack.
