What is a direct currnet?
Direct current is a flow of electricity which only goes one way. Batteries, for example, produce direct current, so the current must flow all the way through a circuit and back into the battery to work. Alternating current is what comes out of a wall outlet, and it alternates in both directions, with current flowing in and out of the outlet.
What current does the television in your living room run on?
AC or Alternating Current. 115 Volts in the U.S. and other parts of the world. 224 Volts in Europe and other countries.
What is the formula for heat flow per unit time through a single layer wall?
Heat flow per area per time = (delta T) / R delta T = difference in temperature between the two sides of the wall area = area of the wall or part of the wall under consideration 'R' = "R"-value of the construction materials and/or insulation that makes up the wall. Intreresting how it's the direct analog of Ohm's Law for electrical voltage (delta T), current (heat flow per time), and resistance ('R').
Does a vacuum cleaner need a magnet to work?
Some kind of magnet or magnetic field is necessary for a motor to operate. Alternating current vacuum cleaners (that plug into the wall) have motors with electromagnets. Direct current vacuum cleaners (that plug into the car's cigarette lighter socket) have motors with permanent magnets.
Why a current wire deflects a magnetic needle placed near it?
A current wire deflects a magnetic needle placed near it because the current wire is creating an electric field. If the current is supplied from an AC (alternating current source as opposed to DC which is direct current- AC would be from a wall socket, DC from a battery), then the current is constantly changing, so the electric field is constantly changing. A changing electric field results in a magnetic field perpendicular (90 degrees) to it. It is actually the magnetic field that is changing the needle direction, because that needle is trying to follow the magnetic field lines (similar to those that you see when you put iron filing near a magnet).

That depends on the municipality. Brandishing them would not be legal; firmly attached to a wall display, they should be legal. Carrying them around in your pocket might just constitute carrying a concealed weapon. Call you local police department's non-emergency telephone number to be certain.

Is it necessary when raising a load bearing wall 4 feet to install a new beam in the exact spot where the wall originally was?
that depends: if it's carrying old dimensional lumber floor or ceiling joists that are lapped at the wall, yes. if it's carrying floor or roof trusses, you may be able to get a repair detail from the truss manufacturer to change the bearing point (inserting a strut in the new location. . .in this case you would still need to build a temporary shoring wall before tearing out the current bearing wall.
What is concealed wiring?
Concealed wiring is wiring that can not be seen. A good example of this is house wiring that is located behind the wall board. The word concealed gets mentioned in the electrical code. It states, that any concealed wiring cannot be covered until the electrical inspector or one of his representatives checks to make sure that the installation is safe to cover.
