Static Electricity and Discharges Quiz

An imbalance of electric charge on a surface that stays put until it suddenly moves

A device that creates static electric charge, often causing hair to stand on end.

Like charges repel each other.

The quick movement of static charge between two objects.

Another name for electric discharge.

The movement of electrons from one object to another during the buildup of static electricity

Not moving; staying in one place

Uneven distribution of electric charge

A natural electric discharge.

Swirling winds separating positive and negative charges in clouds.

Located at the top of clouds.

Located at the bottom of clouds.

A sudden, bright flash of light caused by a surge of electrons traveling between two charged objects.

The loud sound caused by the rapid expansion of air heated by lightning.

A type of film that uses static electricity to adhere to surfaces, often used for signs, decals, or window coverings.

A machine that uses static electricity to transfer toner onto paper, creating a copy of an image.

Positively charged ink used in photocopiers that is attracted to the negatively charged image on the drum.

Packaging designed to protect electronic devices from electrostatic charges.

Harmful imbalances of electrical energy.

Items like computers, video games, etc.

Plastic bags used for protection.

Using environmentally friendly materials (like paper).

Difference in electrical charge between a cloud and the ground that potentially causes a lightning strike.

A powerful electric discharge from a cloud to the ground.

A laser printer uses static electricity to transfer toner onto paper. It starts by using a laser to create a negative image on a positively charged drum. The drum then rolls across positively charged toner particles, which stick to the negatively charged image. Finally, the drum rolls across negatively charged paper, causing the toner particles to transfer to the paper, creating the printed image.

Static electricity is an imbalance of electric charge on the surface of an object. It's like a buildup of extra electrons or a shortage of electrons on the surface of an object.

Toner is a fine powder made of plastic particles, while ink is a liquid. Toner is used in laser printers and sticks to the paper due to static charges, whereas ink is used in inkjet printers and dries on the paper.

When warm, moist air rises and collides with ice crystals in the cloud, it causes the separation of electric charges. The top of the cloud becomes positively charged, while the bottom becomes negatively charged. This uneven charge distribution can lead to lightning.

An electric discharge is the sudden movement of electrons between two objects with different charges. It's the way static electricity is released.

Electrostatic discharge (ESD) can damage sensitive electronic components in computers. As a result, computer technicians take precautions to prevent the buildup of static electricity, which can cause unexpected discharges and damage sensitive parts.

The negatively charged drum acts as a temporary image carrier. The laser creates a negative image on the drum by neutralizing selected areas, making them receptive to the positively charged toner particles.

Negatively charged objects have an excess of electrons, while positively charged objects have a shortage of electrons. In a laser printer, the laser creates a negative image on the drum, which attracts the positively charged toner particles.
