What is brass conductivity?

User Avatar

Asked by Wiki User

Brass has a moderate electrical conductivity, approximately 28% of the International Annealed Copper Standard (IACS). This means that brass is not as conductive as pure copper but can still be used in electrical applications where high conductivity is not required.

What is produced when static electricity is discharged in the air?

User Avatar

Asked by Wiki User

When static electricity is discharged in the air, it can produce a visible spark or a crackling sound. This occurs as the built-up electric charge is neutralized by moving from one object to another, usually through the air.

How does rubbing one object on another create static electricity?

User Avatar

Asked by Wiki User

the electrons get ripped off one object and held by the other

The rubbing moves electrons to the object that holds them more tightly.

What are methods of magnetisation and of demagnetisation?

User Avatar

Asked by Wiki User

Methods of magnetization include running an electric current through a coil of wire to create a magnetic field (electromagnetic), rubbing a magnet against a ferromagnetic material (contact), and exposing a material to a strong external magnetic field (induction). Demagnetization can be achieved by heating the material above its Curie temperature, applying an alternating magnetic field to cancel out the existing magnetization, or subjecting the material to mechanical shock to disrupt the magnetic domains.

Why does rubbing your hair with a balloon cause static electricity?

User Avatar

Asked by Wiki User

This has to do with the charge of the objects. Positively charged items stick to negatively charged items (think "opposites attract"). Though objects like hair and balloons are generally neutral (without a charge) and do not attract anything, this can be changed through the transfer of electrons. Electrons are negatively charged subatomic particles that can be transferred between items through contact.

When you rub a balloon on your hair, the contact between your hair and the balloon allows electrons to be transferred, known as the triboelectric effect. Some materials are more likely to gain electrons and become more negative, while others are more likely to lose electrons and become more positive. In the case of hair and a balloon, the electrons are transferred from your hair to the balloon, so the balloon becomes negative.

Now that electrons have been transferred, your hair and the balloon are of opposite charged and attract one another; therefore, your hair sticks to the balloon. Before the balloon contacts the hair, they both have a stable balance of electrons and protons. Once the balloon is rubbed on the hair, it takes electrons from the hair. Thus leaving the hair positively charged and the balloon negatively charged. Once the balloon is pulled away the hair sticks to it. This happens because opposite charges attract and since the hair was positively charged, and the balloon is negatively charged, they attract.

The study of physics?

Asked by Wiki User

Physics is the natural science that studies matter, energy, and the interactions between them. It seeks to explain the fundamental principles governing the universe, encompassing everything from the smallest particles to the largest galaxies. Through experimentation, observation, and mathematical modeling, physicists aim to understand the underlying laws and mechanisms that govern the physical world.

What happends when an electric current passed through a piezoelectric crystals?

User Avatar

Asked by Randomanswers

When an electric current is passed through a piezoelectric crystal, the crystal experiences mechanical deformation or vibrations due to the inverse piezoelectric effect. This effect causes the crystal to change shape or generate vibrations in response to the electrical input. Conversely, when the crystal is mechanically stressed, it generates an electric charge along its surface due to the direct piezoelectric effect. This dual behavior allows piezoelectric crystals to convert electrical energy into mechanical motion and vice versa.

What does diffracted mean?

User Avatar

Asked by Wiki User

"Diffracted" refers to the scattering or bending of waves as they encounter obstacles or pass through small openings. Diffraction can cause wave interference patterns to form, altering the direction and intensity of the waves.

Are body fluids good conductors of current?

User Avatar

Asked by Wiki User

Yes, body fluids like blood and sweat are good conductors of electrical current because they contain electrolytes that can facilitate the flow of electricity. This is why it is dangerous to be in contact with electrical sources when wet or if there is blood present.

What does newtons law of inertia apply to?

User Avatar

Asked by Wiki User

Newton's First Law of Inertia applies to objects at rest staying at rest and objects in motion staying in motion unless acted upon by an external force. It describes the concept of inertia, which is the tendency of an object to resist changes in its motion.

When static electricity is discharged rapidly what forms of energy can be produced?

User Avatar

Asked by Wiki User

When static electricity is discharged rapidly, it can produce electromagnetic radiation, heat, light, and sound energy. These forms of energy are a result of the rapid movement and release of electrons during the discharge process.

What is the name of something that is not magnetic?

User Avatar

Asked by Wiki User

Non-magnetic materials, such as plastic, glass, wood, and paper, do not have magnetic properties and are not attracted to magnets.

Why does static electricity and wood stick together?

User Avatar

Asked by Wiki User

Static electricity can build up on the surface of wood due to friction, such as rubbing a balloon against it. The wood becomes negatively charged, attracting positively charged particles in the surrounding area. This attraction between the charged wood and other objects leads to the sticking together due to the electrostatic force.

What is minute electric field?

User Avatar

Asked by Wiki User

A minute electric field is a very weak electric field that has a small magnitude or strength. It is often measured in tiny units of electric field strength, such as millivolts per meter or microvolts per meter. Despite its small size, minute electric fields can still have important effects in certain scientific experiments and technologies.

How a magnetic field is created and how its strength is affected?

User Avatar

Asked by Wiki User

A magnetic field is created by moving electric charges, such as electrons. The strength of a magnetic field is affected by the distance from the source, the amount of current flowing, and the material through which the magnetic field is passing. Increasing the current or using materials with higher magnetic permeability will result in a stronger magnetic field.

Is there any law similar to coulomb's law of electrostatic that shows force between magnetic poles?

User Avatar

Asked by Wiki User

Yes, there is a law similar to Coulomb's law for electric charges, known as the Biot-Savart law, that describes the force between magnetic poles. It is based on the concept of magnetic fields generated by currents and is used to calculate the magnetic force between magnetic poles or current-carrying wires.

Is lightning current or static electricity?

User Avatar

Asked by Wiki User

Both. A lightning bolt has many thousands of amps at millions of volts. The planet spins, but also has stationary waves through which it spins. It also has friction. Both of these cause the potential in the air to rise, as well as the earth. And yes..the earth has electricity in it. We don't create electricity from nature. We simply borrow it, make it do our bidding, and return it to ground...or "earth"

Can an umbrella get hit by lightning?

User Avatar

Asked by Wiki User

While it is possible for an umbrella to get hit by lightning due to its metal frame, the likelihood is low compared to taller objects like trees or buildings. It is generally safe to use an umbrella during a thunderstorm, but it is recommended to seek shelter indoors to avoid any risk of being struck by lightning.

Are there positive and negative magnetic charges analogous to positive and negative electric charges?

User Avatar

Asked by Wiki User

No, there are no isolated magnetic charges that are analogous to positive and negative electric charges. Magnetic fields always exist as dipoles with a north and south pole connected together, whereas electric fields can exist as isolated positive or negative charges. This fundamental difference is a key distinction between magnetism and electricity.

What impact does edge effect have on electric fields?

User Avatar

Asked by MSaad

Edge effect can cause distortion and interference in electric fields near sharp edges or boundaries of conducting materials, leading to non-uniform electric field distribution. This can affect the accuracy and efficiency of electrical devices, especially in high-frequency applications where edge effects are more pronounced. Proper design techniques, like adding shielding or rounding edges, can help minimize these effects.

Explain how electrostatic dust preciptators remove smoke particles from chimneys?

User Avatar

Asked by Wiki User

Electrostatic dust precipitators use an electric field to charge particles in the smoke as they pass through. The charged particles are then attracted to oppositely charged plates within the precipitator, causing them to stick to the plates and be removed from the smoke. This process effectively captures and removes smoke particles from the chimney emissions.

Why a static charge does not emit radiation?

User Avatar

Asked by Wiki User

A static charge does not emit radiation because it does not involve the accelerating or decelerating motion of charged particles, which is necessary to produce electromagnetic radiation. In a static charge situation, the charges are stationary or in constant motion, so there is no changing electric or magnetic field to generate radiation.
