Electrostatics

Faraday's dark space is created in a gas discharge tube when electrons gain enough energy to collide with gas atoms, causing them to emit light. The dark space is a region near the cathode where electrons lose energy due to collision with gas atoms, causing a decrease in electron density and subsequent decrease in light emission.

This happens because glass is a good insulator of electricity, allowing charges to move freely within the rod itself but not to transfer to or from other materials easily. Thus, when rubbed with cotton, the glass rod retains the charges instead of giving or receiving them.

1. Electric field lines of force originate from the positive charge and terminate at the negative charge.

2. Electric field lines of force can never intersect each other.

3. Electric field lines of force are not present inside the conductor, it is because electric field inside the conductor is always zero.

4. Electric field lines of force are always perpendicular to the surface of conductor.

5. Curved electric field lines are always non-uniform in nature.

They don't. If there is an electric field, any electric charge will be subject to a force, and therefore to an acceleration.

Only in the special case that the charges are on the surface of a good conductor, they won't move because the charges quickly move to a state of equilibrium. In other words, once such a balance is reached, they won't move around any more.

When the air is dry static electricity is more enhanced and noticeable than when the air is humid. Things with the same charge repel each other. You can produce static electricity by rubbing a balloon in your hair. It will cause your hair to stand up and the balloon will be able to stick to a wall. Also if you have on rubber sole shoes and you drag them along a carpet the first person you touch will be shocked by static electricity.

Electric field lines are drawn to represent the direction of the electric field at various points in space. They follow specific rules: they originate from positive charges and terminate on negative charges, they never intersect, the density of lines indicates the strength of the electric field, and they are perpendicular to the surface of a conductor at equilibrium.

An electroscope detects an electric charge by using the principle of electrostatic induction. When a charged object comes near the electroscope, it induces a separation of charge within the electroscope, causing the leaves to either repel or attract each other depending on the type of charge present. This movement of the leaves indicates the presence and type of electric charge.

Yes, you can flash a fluorescent tube with static electricity. Once the static potential difference is equalized the tube will go out.

Static electricity is discharged with a spark in a fraction of a second. Florescent bulbs stay on for long periods of time. Perhaps it could operate a strobe light one time every few minutes. A strobe light does not provide enough light to be useful for anything except photography and dancing at a club!

When a positively charged body is brought close to a gold leaf electroscope, the electrons in the electroscope will be repelled towards the top of the leaves, causing them to diverge. This happens because like charges repel each other, and the positive charge on the body repels the electrons in the electroscope leaves.

Helicopters generate static electricity due to the friction between the rotor blades and the surrounding air. This friction causes a build-up of electric charge on the blades, which can discharge as a spark when the helicopter lands or when personnel come in contact with it. Grounding systems are used to prevent static electricity build-up on helicopters.

Static electricity and current electricity are both forms of electrical energy. They both involve the movement of electrons, but in static electricity, the charges accumulate on an object and do not flow, while in current electricity, the charges continuously flow in a circuit.

Static electricity is created when two materials rub against each other, causing electrons to move from one material to the other. This imbalance of electrons results in a buildup of static charge on the surfaces of the materials, which can then discharge as a spark or shock when they come into contact with a conductor.

The form of stationary electricity is called static electricity. It occurs when there is an imbalance of electric charges on the surface of an object.

The value of relative permittivity for insulating materials is typically in the range of 2 to 10. This value indicates the material's ability to store electrical energy when an electric field is applied. Higher values of relative permittivity indicate better insulating properties.

Static charge is the imbalance of electric charge on an object. Objects become statically charged when electrons are transferred between two objects through friction. Like charges repel each other, while opposite charges attract. Static charge can build up on insulating materials and can be discharged through a spark if the potential between two objects is high enough.

Electrostatic shielding is a technique used to prevent electric fields from penetrating or affecting a specific area by surrounding it with conductive materials. This is commonly used in electronic devices to protect sensitive components from external interference and to ensure proper functioning. The conductive material acts as a barrier to redirect or absorb the electric fields, reducing the impact on the protected area.

The gold leaf on an electroscope lifts when a charged object is brought near because the like charges repel each other. The charged object induces a charge separation in the electroscope, causing the gold leaf to become charged and repel away from the object.

The electrostatic potential is a scalar quantity that represents the potential energy of a unit positive charge at a specific point in the electric field. It is defined as the work done in moving a unit positive charge from infinity to that point. This potential does not depend on the path taken and can be defined at any point in a region of space regardless of the presence of an electric field.

They are connected in 'series', the negative terminal of one cell connected to the

positive terminal of the next cell, and so on with as many cells as you have, so that

there is only one path for current through the entire combination of cells.

In this configuration, the EMF of the combination is the sum of the individual EMFs, but

the combination can't deliver any more current (amperes) than any single cell can.

A capacitor can't deliver electrical energy 'constantly'. Much like a battery, electrical

energy can be stored in it, and then delivered later.

The capacitor only stores some definite amount of energy ... equal to 1/2 of its capacitance

multiplied by the square of the voltage to which it's charged ... and later, after it has

delivered that amount of energy, it delivers no more without being charged again.

When you rub one balloon with wool, and then rub another balloon with wool,

we can safely assume that both balloons acquire the same kind of charge. So

when you try to bring them together, they'll repel each other (push apart).

If you are asking "Do lasers run on electricity?" Then the answer would be "Yes, Most of them do."

Yes, when a plastic ruler is rubbed with oily hair, it can become statically charged. This static charge may attract lightweight objects like pieces of paper due to the electrostatic force between the ruler and the paper.

Current electricity is the flow of electrons through a conductor, while static electricity is the buildup of electric charge on an object. Both are manifestations of the fundamental force of electromagnetism. Static electricity can discharge to become current electricity under certain conditions.

Electrostatic forces repel the nanoparticles from each other due to their like charges, preventing them from aggregating. This repulsion helps maintain the stability and dispersion of the nanoparticles in a solution by keeping them evenly distributed and separate.
