Can you do it - yes. SHOULD you do it - NO. Because brass and galvanized conduit have different electrochemical potentials (go talk to a chemistry teacher if you need an explanation of electrochemical potential) if you place them in direct contact with each other, you will set up a galvanic differential and promote corrosion. If you must connect brass and galvanized conduit, you should use a connector between the two that will isolate them electrically from each other. In essence, you are "insulating" them from each other so that you don't get an electric current between them to promote corrosion. There are special fittings, I believe they are referred to as "dielectric fittings" that are designed to provide this insulation and avoid the problem of galvanic corrosion. The more corrosive the liquid you have in the pipes, the more important it is to use these special fittings. Hard or salty water can particularly problematic.
Completely isolate the electrical circuit - so use some insulation such as PVC to ensure the metals are not in contact - but the above situation should not be allowed in the first place - very poor design indeed.
The main difference between wrought and forged fittings is strength. Forged fittings are tougher than wrought fittings as they begin as a casting which is then forged which adds to its durability.
The dielectric,usually the insulator between the plates of a capacitor, can be overstressed by the application of too high voltages applied to the capacitor plates. The dielectric breaks down and a current flows between the plates until,either they are discharged, or an equilibrium is reached,below the working voltage of the capacitor. If the dielectric is damaged in this process he capacitor must be replaced. Some dielectric material self heal and can recover from an over voltage.
Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.
Yes, need one between the two dissimilar metals.

there are several... ask these people, our company uses them http://www.StoneSheets.com
The difference between 18 gauge and 22 gauge stainless steel is the thickness. The 18 gauge is 0.050" thick, and the 22 gauge is 0.031" thick. A link is provided below to an article with a list of the conversions. You'll note that the cited thickness for the gauges of stainless do not apply to galvanized steel, aluminum, zinc, brass or other metals.
What is the difference between complex permittivity and static dielectric conatant?
Yes and no. Pipes are pipes and many houses have both copper and galvinized. But copper and galvinized pipe must never come into direct contact with each other. You have to put what's called a dielectric fitting (available at your local hardware store) in between them. The problem is that without a dielectric fitting you'll get what's called electrolysis. Electrolysis eats holes in your pipes. Like I said, just put in a dielectric fitting. No sweat.

capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.

Galvanized steel sheet is basically indistinguishable from zinc steel. If you want to buy galvanized steel sheets. You can go to Shanghai Changzheng, which is the choice of most people for its superior quality steel sheets.
