It holds AC energy and passes DC. This will take the ripple out of DC circuits.

How do radioactive rays behave in an electric and magnetic field?
That will depend on their electric charge: plus and minus charged rays will behave in opposite ways while uncharged rays will not be affected at all by the fields.
What is the fundamental rule for electric charge?
Fundamental laws of electric charges: opposite charges (positive and negative) attract, similar charges (positive and positive or negative and negative) repel, somtimes charged objects will attract a neutral object.
Is it dangerous to play the piano when there is lightning?
Only if you are playing it outside. It has no electric charge. However, if you are going to shower whem there is lightning, you are in more danger moreso if you are playing a piano.
Why does water have surface question?
I think you mean surface tension. Water has surface tension because water is a polar molecule, meaning the opposite sides of the molecule do not share electrons equally. This means that one end of the water molecule has a positive charge and the other has a negative one. The Law of Electromagnetic Force tells us that opposite charges attract each other. So, at the surface, where there is no water above it, the top layer of water molecules allighn themselves and because of the attractive forces in the charged particles, they "stick" together. This is surface tension.
What material blocks radio waves best?
As Faraday showed, an electric charge cannot exist inside a container. Mutual repulsion pushes the charge to the largest surface.A Screened Room may be constructed of a double layer of fine metal mesh screening, with these two screens connected at a single point.Now, since there cannot be any charge difference between these two connected cages, there cannot be any flow of charge across the space between the two cages. Thus this construction effectively screens the contained room from e-m waves.
A shortage of electrons on the surface creates an electric?
charge
Can Gauss's law be applied to sheet of charge?
no gauss low is only applicable for closed paths. a plane sheet is not a closed path. for applying gauss law the charge must be inside the closed loop or path... ========================== I'll say "yes". Gauss' law says that the electric flux through a closed surface is proportional to the amount of charge inside the closed surface. The shape of the surface doesn't matter, and the shape of the charge distribution inside it doesn't matter either. If a closed surface encloses a part of a sheet of charge, then the flux through the surface is proportional to the amount of charge that's on the part of the sheet inside the surface. That doesn't bother me at all.
Electric charge is uniformly distributed on the surface of a spherical balloon. Show how electric intensity and electric potential vary (a) on the surface (b) inside and (c) outside?

A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
What is the build up of a positive or negative electric charge on a materials surface?
Static
What is the Difference between line charge density and surface charge density?
The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward. The electric flux is then just the electric field times the area of the cylinder.
Does charge get redistributed over the surface of conductor why?
You need to define your querstion a little more. Are we talking about an electric current, or a static charge?
What is electrostatic attraction?
An electrostatic force attracts oppositely charged particles.
Does your body have electric charge?
yes your body is both negatively charged and positively charged on the extracellular surface
What is the electric field on the surface of the conductor?
The field is zero inside only if any charge is evenly distributed on the surface. That's a mathematical theorem, sorry I don't have the proof handy. But when you measure the electric field inside a charged sphere, the charge you use might be large enough to redistribute the surface charge. In this case the electric field will not be zero. Only if you measure at the centre.
Earth's surface has an excess amount of negative charge?
Yes the Earth has a vertical electric field that points down. So if you were to try and calculate the amount of excess charge on the Earth's surface, you would get a negative value.
What are the kinds of electric charge?
The kinds of electric charge are positive charge and negative charge
