Electrostatics

The heat produced by an electric current depends on the resistance of the material through which the current is passing, the square of the current flowing through the material, and the duration for which the current flows.

Any material electrically separated from ground will hold a static charge, even the human body, but only some materials can genate a static sharge in the first place by friction.Run a clear bic ballpoint pen over your hair then hold it close to a fine dribble of water from the tap. It will bend the water because of its static charge. Once the water touches the pen, the charge escapes through the water, up into the tap and then into the earth via the pipes. Note only some plastics generate a static charge in this way.I believe that some materials hold a negative static charge, while others (glass?) hold a positive charge. Not sure though.

They attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.

Inside a photocopier is a drum, which can be charged with static electricity, and photocopier toner, which is a fine black powder. When parts of the drum are charged, the toner is attracted to them. Light is moved across the document to be copied, and where blank paper is found, reflected back onto the drum. This cancels out the charged parts, and the toner is then spread over the drum, sticking to any parts left. (i.e., the black parts on the original document.) Paper passed through the photocopier machine is then charged so that the toner on the drum is attracted to it. The paper is then heated so that it fuses to the paper to form a replica of the original document.

Electrostatics can be measured using tools such as electrostatic voltmeters, field meters, or charge plate monitors. These devices detect and quantify the presence of electric charge or static electricity in a given area or object. Measurements are typically reported in units of voltage, charge, or electric field strength.

A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery).

note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.

This has to do with the transfer of electrons from one material to another through the contact of the materials. The transfer of electrons is static electricity, and because some materials have a higher tendency to gain or lost electrons than others, more or less static electricity is produced.

Wool has a tendency to gain electrons. Both metal and plastic lose electrons; however, plastic has a far higher tendency to lose electrons than does metal. This is shown on the triboelectric series, a chart showing the relative tendencies of various materials to transfer electrons. Because plastic will lose more electrons to the wool than the metal will, more static electricity is produced.

As we know that like charges repel each other therefore if two negative charges are placed they will repel each other.

Same poles attract where as opposite poles repel.

N-N= repel

N-S=attract

S-N=attract

S-S=repel

Objects can obtain a static charge through a process called triboelectric charging, where two objects rub against each other and exchange electrons. This leads to one object becoming negatively charged and the other positively charged due to the unequal sharing of electrons.

A VERY BIG PROBLEM practically all electronics are restricted to voltages no greater 40 50 volts electrostatic can be as much as 5kv to 50 kv but the source impedance is very hi so while the voltage is there current capabilities are not a low impedance device can possibly survive these discharges but a hi impedance device like MOS cannot survive since the negligent current will raise the potential very hi blowing the device.

The generator transformer is the first essential component for energy transmission, allowing energy supplied by the generator to be transferred to the network at the required voltage.

The generator transformer is the first essential component for energy transmission, allowing energy supplied by the generator to be transferred to the network at the required voltage.

This is a type of Power Transformer where the LV winding is connected to the generator through the bus duct and HV winding to the transmission system. In addition to the features of Power Transformer, our Generator Transformer is designed to withstand over voltage caused by sudden load throw off from the generator. It is built as a single or three phase unit and located in power stations.

The process of electricity flowing through materials such as copper or aluminum. Not so useful. Better: Conductive materials are rated for their ability as a conductor, usually wire is the cheapest. The more useful ratings are voltage and amperage.

Air Fresheners use static electricity by charging the air/odour molecules in the room. A plate on the air freshener is then charged oppositely. When this happens the air/odour molecules will attract to the plate removing the smell and replacing it with a fresh scent. So instead of the air freshener producing a stronger smell, it will eliminate the odour.

Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects.

Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.

It is impossible

There are two types of charges of ions that are the negative and the positive charges. Ionic bonding is between 2 types of elements;the metals and non-metals. Metals loose electrons while non-metals gain electrons. when they form ions they obtain charges. The metals always gain a positive charge as they loose electrons while the non-metals always gain a negative charge as they gain electrons.

-- Any energy dissipated by the conencting wires is lost from the circuit, and unavailable to do the job for which the circuit is intended. The less resistance the connecting wires have, the less energy they'll dissipate. So the connecting wires need to have as little resistance as possible.

-- Copper is easy to work, easy to form wires from, and is the second-best electrical conductor known, after silver. Copper is used instead of silver because it costs less.

-- The thicker any wire is, the less resistance it has.

To be statically charged means that an object has more of one type of particles than another.

For example, if an object with more electrons than protons is negatively charged so we say that the object has built up a static charge.

"Static electricity" is more accurately called "static charge" and refers to a body having a surplus of free electrons (negative) or a shortage of free electrons (positive).

Friction between the two objects strips electrons from one object to the other.

this is because when two objects rub electrons are being passed on to the other object making it cause a temperary side affect.

there are three ways of doing this...

Friction---- Rubbing together

Contact---- Touching together

and induction-----not touching object etc

This is a definition of "ionic bonding".

Lightning in itself IS static electricity. The only difference between lightning and the little zap you feel when you rub your feet on your carpet and touch something metal is that Lightning is MILLIONS of times more powerful.
