​Which of the following objects is electrically neutral?
Which of the following objects is electrically neutral?
When an object has more electrons than protons, it is _______________ charged.
What will occur when the two spheres shown here come in contact with each other?
Lightning is caused by ______________ electricity.
Which of the following methods are ways to charge an object?
When neutral rubber rod and neutral wool are rubbed together, electrons on the wool are transferred to the rubber rod, and the rubber rod is charged ______________.
_________________electricity is the flow of electrons through a conductor.
After being rubbed through the hair, a plastic comb can attract small pieces of paper.
This charging method is called charging byÂ
All conductors conduct electricity equally well.
Insulators are important to protect us from getting electrocuted.
Electrons can move easily in metals so metals are usually good insulators.
Identify the objects as either conductor or an insulator.
Materials such as steel that electric current flow through them easily are called
Materials such as wood that electric current cannot flow through them easily are calledÂ
All materials are made of atoms.
Atoms contain charged particles.
Electrons and neutrons are opposite charges that attract one another.
If a neutral atom gains electrons, it becomes a positively charged ion.
The closer two positive charges become to each other, the greater the repulsive force between the charges.
What device is used to measure electrical charge?
