Describe how an electrscope works to detect static electricity?

There are different types.\n\nHowever, the gold leaf electroscopes have two very thin leaves (not necessarily made of gold) attached to a conductive rod. The rod has a metal knob at the other end.\n\nWhen some charge is imparted to the knob, the charge flows to the leaves. As the two leaves same type of charge (either positive or negative), they repel each other.\n\nAmount of charge can be estimated by the amount of separation of the leaves.

its just static electricity as far as I know caused by friction such as when you rub a balloon on your head and your hair raises. Also our bodies are naturally full of electricity

As you are building a computer, ESD sensitive parts can get damaged.  You can buy an ESD wrist strap and hook it to the AC outlets center screw (between the two plugs).  This will let the static electricity discharge through ground and not hurt your components.

Ok. Try This.....\n\nStart with a clear glass or plastic jar, some stripped wire, a strip of aluminum foil, and a larger piece of aluminum foil. \n \nBend the wire over the top of the jar so that it goes over the middle and is wrapped around the opening of the jar. Now fold the aluminum foil strip over and drop it over the wire, so that it hangs down into the jar.  \n\nNext take the larger piece of aluminum foil: make it roughly circular by cutting or folding the corners underneath, and press it over the top of the jar. Next wrap electrical tape (or any tape) over the edges of the aluminum foil holding it to the jar. Finally smooth out any bumps in the foil. \n \nYour electroscope should look something like this. \n \nComb your hair a few times and hold the comb close to the top of the electroscope. The ends of the aluminum foil should push away from each other because of electric charge. \n \nYou can discharge the scope with your hand while holding the comb close to the top of the scope. \n \nMove your hand away. \n \nMove the comb away. \n \nA charge has been induced into the electroscope. When you were discharging the scope charge remained close to the comb and when you moved the comb away that charge was released to spread through the rest of the metal parts including the aluminum strip. \n\nHope this helps.

ok its all about static electricity see if you rub a ballon aganist your hair it will become charged (-). And so will attached to a wall since it is electricty charged and will be attracted by the walls protons (+) charge

How will he SHOW that an electric current has been produced? It won't be sparking or anything like that.\n\nHere's a very crude, but effective way to prove an electric current has been produced. Buy a D-sized battery and some non-insulated wire. Using thick gloves, place one end of the wire on the + side of the battery and the other end of the wire on the - side. Hold them in place. Almost immediately, the wire will become very hot. The heat produced is due to friction. The electrons (electric current) traveling from one end of the battery to the other rub against the particles that make up the wire. The rubbing produces heat, like when you rub your hands together really fast.\n\nAs an added bonus, wrap that same wire around a galvanized nail about 8 times, (be sure to leave both wire ends free)then repeat the steps above. The nail becomes magnetized and will pick up paper clips. The more coils you wrap around the nail, the more magnetized it will be. This is called an electromagnet because a magnet was produced by an electric current.

Volts-drop test.\n\nPut the armature on a V-block powered by a regulated voltage source.  Check the voltage across 2 adjacent com segments and repeat as you rotate thru 360 degrees.  They should all be the same.

Hi!\nAre you asking about Extra Sensory Perception or Electro Static Precipators or Encapsulating Security Payload. The Extra Sensory Perception is questionable as to its' existance. You would have to ask someone who is an expert in the study of mind signals. This is kind of like psychics who predict the future. If they were really able to do it, you would read of a psychic winning a lottery. Hasn't happened yet! \n\nfor more information:\nhttp://activistnation.net/ESPMISSION.html\n\nElectro Static Precipitators on the other hand work very well. People have been using them for years to clean particles out of exhaust flues of power houses and other smoke producing processes. The principle is to use an static field to charge the particles in a gas or smoke stream. The particles are then collected on an oppositely charged plate. In one company I worked for, the plates were cleaned by electrically lifting a steel bar above the plate and dropping it onto the edge of the plate. The accumulated particles then dropped into the collection bin at the bottom.\nThe space between the charging plates depends on the concentration of particles, and the voltage. In one application, the cleaning of cigarette smoke of particulates, the voltage-spacing trade-off is critical. I remember sitting near one, and periodically it sparked over, like a mineature lighting bolt.For one application see:\n\nhttp://www.netl.doe.gov/technologies/coalpower/ewr/mercury/control-tech/pubs/AQIV-Reynolds.pdf\n\nFor the Encapsulating Security Packet I suggest that  you consult the specification at:\n\nhttp://www.faqs.org/rfcs/rfc2406.html\n\nI hope that this helps.

ADF's detect an electric field and a magnetic field which are perpendicular in space and their amplitudes vary sinusoidally with time. The magnetic field induces a voltage into the windings of the ADF loop antenna. By measuring the phase difference between the windings the ADF is able to determine the direction of the beacon. \n\nPutting beacons around the house and using ADF to navigate turns out to be expensive and inefficient as GPS and proximity sensors are available and work better.

a belt is driven across a surface rubbing the two together to make 'static', which is basically just free electrons. they collect in the big metallic ball, and when the potential is high enough between the ball and another conductor (or a conductor is brough close enough), the electrons 'jump the gap' to get to ground, and you see the big spark!\n\nWant to build one? Here's how:

make and working elctric circuit like a bell, r a bulb, u can Also explain working of an electromagnet using a model.\nu can also expain the capillarity concept

think so... we all have static electricity in our body...

Here is a good article. To understand them, you need to get a multimeter, and electronics projects book, a breadboard (to mount circuits on), and a selection of electronic parts from Radio Shack. Use batteries initially, and then when you are more confident a power supply and rectifier to do experiments, and measure voltage, current, and resistance values around the circuit.\nhttp://en.wikipedia.org/wiki/Electronics\nHyperphysics.

Static electricity is simply an electric charge. Yes you can collect generate and use an electric charge to power things. What is generally referred to as static electricity is an electric charge that is developed as an incidentally.

yes every thing i touch schocks me  \n\nWe usually only notice static electricity in the winter when the air is very dry. During the summer, the air is more humid. The water in the air helps electrons move off you more quickly, so you can not build up as big a charge.
