What branch of science studies heat electricity and magnetism?
The branch of science that studies heat, electricity, and magnetism is physics. Physics encompasses the study of the fundamental principles that govern these phenomenon and how they interact with each other.
Can static electricity hurt someone?
While static electricity can cause a mild shock, it is typically not powerful enough to cause serious harm to most people. However, in rare cases, strong static discharges can potentially ignite flammable gases or cause damage to electronic devices. It's more of an annoyance than a serious safety concern for most individuals.
IS chlorine a good conductor of heat and electricity?
Chlorine is a poor conductor of both heat and electricity. It is a nonmetal with low electrical conductivity and thermal conductivity due to its atomic structure and lack of free-moving electrons.
How do you rewire a 220 volt motor to run as a 110 volt motor on a old Howell electric motor?
Determine which leads are run leads, and which are start leads, or which are a combination of both. Once determined the overall solution is to parallel the windings externally, where at a higher voltage 1 motor lead per line is used, 2 would used per line in parallel.
Leads marked 1 through 4 would be connected 1 to line, and 4 to line with 2 and 3 electrically connected and isolated as a series connection for the higher 220 single phase voltage.
Rewire or reconnecting if possible to 110 would then be connected motor lead 1 and 3 to one of the 110 volt lines and the remaining motor leads 2 and 4 to the other 110 volt line.
In some cases the parallel connection could be 1 and 2 to line, and 3 and 4 to line for 110 volts.
It makes no difference on an induction single phase motor which line from the 110 either hot or neutral is connected to either pair of motor leads.
Compare and contrast static electricity and electricity that flows through wires?
Electricity that flows through wires is very specific. It's input is controlled and regulated. Every aspect is known, current, voltage, resistance, frequency, etc. The main difference though is the way it is generated. Hard wire electricity can be generated in a number of ways; usually some form of chemical energy is converted to kinetic energy where a difference in permanent magnets through a coil will generate the electricity. In one other commonly used way the electron flow is chemically generated through a difference in valance electrons (also known as a battery).
Static however is only categorized differently because of the way it is produced and the proportions in which it is delivered. Static is generated through friction of one surface that is a good conductor and one surface that is a very bad electrical conductor. And also the fact that static will build up to 30,000 volts (at low current delivery) and flows in no specific direction, unlike a hard wire.
The material is most likely a nonmetal. Nonmetals are typically nonmagnetic, can be found in gaseous form, and do not conduct heat or electricity well. They often react with other elements to form compounds.
How many electrical paths are in a parallel circut?
In a parallel circuit, each component is connected directly to the power source, resulting in multiple electrical paths. The number of electrical paths in a parallel circuit is equal to the number of components connected in parallel.
How electrical activity of neurons might be measured?
The information each neuron processes determines how strong the action potential (electrical current) is within each neuron. An example of studying the electrical activity is by using temperature. The neurons which detect the temperature change are called sensory neurons. If you stimulate the neurons by leaving your fingertip in cold water for an adequate amount of time the electrical current within each neuron is increased as the temperature of your fingertip drops. The neurons within the fingertip sense the temperature drop and emit the electrical current, then the next neuron senses the temperature drop as the fingertip is held in the cold water and emits a stronger electrical current, the colder temperature in the next neuron as your finger is held in the water emits an even higher frequency and so on until the message arrives at the spinal cord and is then sent to the brain through the now very strong electrical current within the neurons informing it of the temperature decrease and then resulting in action outcome.
What is electric lines of force?
electric lines of force are imaginary lines defined by the paths traced by unit charges placed in an electric field. Lines of force are everywhere parallel to the electric field strength vector. Their principal use is as a convenient means of picturing the geometry of an electric field.
Electricity has become a household necessity in many places around the globe. It is used to power everything from batteries in a child's toy to powering NASA's super computers. So, why is it useful? It has people bound to their couches watching television. It has people up in the middle of the night instant messaging to friends halfway across the globe. It even has people of all ages glued to iPods, PSPs, laptops and much more. Even so, electricity does have its uses. It powers your ICU machines in the hospitals. It powers the computers of every airline on the planet allowing us to fly safely through the skies without fear of crashing into another plane. It powers the this simple household computer from which I am typing and allows you, where ever you are to ask this question; and me to answer it as best I can. So, electricity is useful.
What affects the resistance of a conductor?
The length and the material that the conductor is made from. Different wire sizes have different ohm/foot. The longer the length of the conductor the higher the ohms/foot. Temperature also affects the resistance. Silver has the least resistance, followed by Copper, then Gold, then Aluminum. Here are some published resistances in micro ohm-cm: Silver - 1.6 Copper - 1.7 Gold - 2.2 Aluminum - 2.7
Why do you use three phase power?
Single phase power has a sine wave voltage that crosses zero before reversing its polarity. In the region near the zero-crossing there is not much power. At zero there is none at all. So single phase loads often need some trickery to deliver output in this area. Often it is just the inertia of the motor or appliance.
Three phase power is always delivering power on one of its phases, and is thus preferred for machines, motors and appliances that use lots of power.
If the application is large power, or small power with weight restrictions (like automobiles!) Three Phase is preferred. DC (Direct Current) is the next step up for smooth high-power devices but requires rectification, regulation and smoothing to be useful.
Another problem with DC is that, for efficient long distance transmission, it cannot be simply converted to much higher voltages than the voltage at which it was generated at the power station. Similarly DC cannot be transformed down to safer, much lower mains voltages for use by consumers.
AC (Alternating Current) is used for high power generation and distribution because it can easily be transformed, using transformers, to achieve very efficient power transmission over very long distances and can then be transformed down to low voltages for distribution to consumers.
Two phase, and higher multi-phases are also used but very rarely.
Another Answer
Because, for a given load, less volume of copper is required to supply that load, making a three-phase system roughly 75% the cost of a corresponding single-phase system.
The name of the gas is Neon. Neon produces a reddish-orange color. Argon produces a faint purple. Krypton produces a ghostly white. Xenon produces a blue glow. No information exists on radon as it is not used in neon signs.
How do you connect wire so that it is not readable by the electricity meter?
This question is asking for instructions on how to do something which is illegal.
No information about that kind of activity is welcome here on WikiAnswers.
This is the only answer to such questions that will be given.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
Why does metal attract electricity?
Metal attracts electricity because it contains a high density of free electrons that can move easily within the material. When a voltage is applied, these free electrons can flow through the metal, creating an electric current. This property makes metal a good conductor of electricity.
What is electric wire insulation made of?
Electric wire insulation is typically made of materials such as PVC (polyvinyl chloride), PE (polyethylene), XLPE (cross-linked polyethylene), or rubber. These materials provide protection against electric shock and prevent wires from coming into contact with each other or surrounding objects.
What effect does heat have on electric current flow?
Increasing heat can increase the resistance of the material through which the current flows, which can reduce the flow of electric current. However, in some cases, heat can also increase the kinetic energy of charge carriers, leading to increased current flow in certain materials like semiconductors.
Is electricity matter or non matter?
Electricity is matter. It is the fourth state of matter called plasma. Stars and lightning are also made of plasma.
What element generally has a shiny luster and is a good conductor of heat and electricity?
The element that generally has a shiny luster and is a good conductor of heat and electricity is metal, particularly metals like copper, silver, and gold. These metals have free-flowing electrons that allow them to conduct electricity and heat efficiently, and their shiny surfaces result from their ability to reflect light.
A material that does not transfer heat very well?
Plastic
Better materials to slow heat transfer through conduction are called heat insulation material, like fiberglass, foam, and historically, asbestos. A trapped air space is also very good, like double pane windows. But radiant heat is best insulated using reflective surfaces separated by a space. The lighter the density of the material between the reflective surfaces, the better the insulation effect. A vacuum between reflective surfaces is ideal. This is often called a thermos. This is what is used to store liquefied gases.
What is an elementary particle carrying a unit charge of negative electricity called?
An elementary particle carrying a unit charge of negative electricity is called an electron.
What is the difference between static and dynamic electricity?
Electricity is a short term of electricity objects for example when we rub our comb or ruler to our hair some of the electrons move to the ruler and because of that it attracts pieces of paper
Dynamic electricity is a flow of electrical energy that occurs in a long period time
There are three variables to make sure that the dynamic electricity to flow:
Voltage:is a term in electricity which represent electrical energy in electron.There are two sides of electricity.There are + and -,where + means the side that has no energy (0 energy) and the - side has the energy of electrons.Energy - attracts with + energy.
Electrical current:The flow of electrical energy per second
Resistance:The obstacle of energy flows.It is occurred on the cables and the electrical appliances
Is Salt Water an insulator or a conductor?
salt water is a good conductor of electricity as it contains sodium and chloride ions to carry out current
How do you find resistance in a circuit?
That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.
