1. What is the main reason for static electricity a) Static electricity is the result of an excess of negative charges on an object b) Static electricity is the result of an excess of positive charges on an object c) Static electricity is the result of an imbalance between negative and ...
静电是指物体表面失去电子而显示正电或者得到电子而显示负电。也就是说只要物体表面的总电荷数不为零的话，就是物体带有静电。静止电荷是指正电荷或者负电荷处于静止状态（比如所受的电场力之和为零时）。静电和静止电荷是两个完全不同的概念 供参考 ...
electric charge - the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; "the battery needed a fresh charge" charge electrostatic charge - the electric charge at rest on the surface of an insulated body (which establ...
electric charge static electricity static electricity refers to an imbalance between the electric charges in a body, specifically the imbalance between the negative and the positive charges on a body. the imbalance in the charge is introduced by physical means. one of the most common causes of ...
But if you rub things together, electrons can move from one atom to another. Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons. They have a positive charge. When charges are separated like this, it is called static electricity. ...
Static electricity is the imbalance of positive and negative charges. Opposites Attract Now, positive and negative charges behave in interesting ways. Did you ever hear the saying that opposites attract? Well, it's true. Two things with opposite, or different charges (a positive and a negative...
A positively-charged comb at the bottom (connected to a supply of electricity) draws electrons from the belt, leaving it with a net positive charge, and this charge is picked up by a comb at the top, which spreads it out to the big dome at the top. If you touch the dome during the...
Electricity Section 1: Electric Charge and Static Electricity Atoms and their charges Atoms: –Protons = positive charge –Electrons = negative charge –Neutrons = no charge –CHARGED OBJECTS EXERT FORCES ON EACH OTHER Law of Electric Charges The type of force between objects depend on the type...
The meaning of STATIC ELECTRICITY is electricity that consists of isolated motionless charges (such as those produced by friction). How to use static electricity in a sentence.
positive charge more protons than electrons negative charge more electrons than protons neutral charge contains an equal number of protons and electrons Conductors materials that allow heat and electricity to pass through it. Insulators materials that prevent electric charges from flowing through them easi...
