What problems are caused by static electricity and what are the solutions?
Many people have static problems, especially in the winter when the indoor air is very dry. But don't worry, static elimination may be easier than you think. There are many steps you can take to eliminate static electricity, and many static control products available.
Static Elimination Tips
Our expert in static electricity in the electronics industry suggests trying the following to get rid of static electricity problems in your home or office:
1) Increase the humidity in your house and workplace. Air is much drier in the winter, which increases the frequency and severity of shocks. Use a humidifier.
2) Change clothes - switch to natural fibres, since synthetics pick up more of a static charge.
3) Change shoes - there are special conductive shoes in a variety of styles. They are made for people working in the electronics industry. You will need to find a store or catalogue that sells or can order them for you. (Search on line for "esd shoes")
4) If your skin is very dry - try an anti-static hand lotion (also available for the electronics industry.)
Here are 3 more suggestions for static control from other sources:
1) Walk barefoot. (Or, as silly as it may sound, cover your shoes with aluminium foil when possible) to reduce the static build up.
2) Wear a thimble on your finger, or carry a coin, and use them to touch grounded metal objects as often as possible. This will not eliminate the static discharge, but will stop the pain you feel in your fingertips.
3) Be sure to ground yourself before touching sensitive electronic equipment.
Why should electricity be used sparingly?
Electrical energy should be used intelligently because at this time the majority of it is generated by burning fossil fuels. These fuels are not replenishable; they also add carbon dioxide to the atmosphere and contribute other pollution problems. From a more personal point of view, electrical energy costs you money. You have to pay for what you waste as well as for what you use intelligently. Wasting electricity (or anything else for that matter) is throwing your money away.
How does sound travel through a microphone?
Sound waves enter the microphone and are then converted to an analog electric current.
What words can describe electricity?
There are many key words to understand when discussing electricity. Electricity flows in a current. The unit of power of electricity is a watt which refers to the rate of work done. A volt is force at which electricity moves from its origin through a conductor and to the place of use.

Why you want to become a teaching assistant?
I enjoy working with children. I am responsible and understanding person and this profession needs both of this qulities. I want to become a teacher and its eassier for me to go step by step to reach to that level. Therefore, i have decided to first work as a teaching assistant. As a teaching assistant I would be working with children and a qulified teacher in the classroom and this would give me a lot of experience to choose my career as a teacher in the future. TA is the enjoyable but at the same time a responsible profession. But those who love to work with children, this is the best profession for them and I am really looking forward to work as a teaching assistant.

Plan to run all of your electrical wires from a central location in your basement. Set aside an open area where you can set up electrical panels if needed. Keep your central location near other electrical furnishings, like the fuse box.

Install conduit before you run any type of wire through your home. This tubing protects the wires in your home and also helps keep them organized and in place. You'll probably want to use a larger diameter conduit for your central vein of wiring, and then branch off with smaller sizes for individual rooms.

Set up at least one electrical outlet and one phone jack in each room. In most rooms, you'll want one electrical outlet on each wall. It's difficult and expensive to cut into drywall and install more outlets later, so you can overestimate how many you'll need.

Put some extra conduit into the ceilings and walls in each room. This preparation will make it much easier to install a multi-room audio system or additional wiring for Internet access later. Tying string off at each of the conduits makes it very easy to pull a new wire through the tubing.

Color-code your conduit and wiring so that you can keep track of what you've installed. An extensive map of your wiring can make fixing subsequent problems much easier than if you didn't know which wires were connected to which rooms.
Identify materials that are commonly used as conductors to provide household electricity?
Non metallic sheathed cable is used as conductors in home wiring.

When is the build up of static electricity indoors usually greatest?
The build up of static electricity indoors is usually greatest in the winter time when indoor heat is on. The home heating drys the air in the house and with a lower humidity the static build up does not dissipate as well as higher humid air will.
How does a frequency drive work?
Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.
How do you insulate an electrical outlet?
If the outlet is on an outside wall there is a plastic boot that goesaround the outlet. The purpose of this boot is to keep the vapour barrier intact. The edges of this boot are then taped to the wall vapour barrier to make a complete air seal. The insulation goes behind the outlet boot which allows the wall R value to remain the same as the rest of the wall.
Is it true or false that electricity is a form of fire?
FALSE. (they are different forms of energy) "Fire" is a release of thermal energy from a chemical or electro-chemical reaction. The ensuing radiation can have visual components (photons) as well as infra-red radiation (heat). "Electricity" is the conductive flow of electrons through a material, medium, or vacuum. Energized electrons (current) flow into a material or device at the anode and out at the cathode.

Is a parallel circuit brighter than a series circuit?
Both are same. Only thing it depends upon the incoming voltage. In series ciruity if one bulb fails, the ciruit continuity breaks . In case of paraleel circuit even if one bulb fails the circuit continuity will not get affected
