Introduction to Electrostatics

Static electricity is a substance that is transferred from one object to another.

Unlike gravitational potential, electrical potential does not depend on height.

Both positive and negative charges are free to move from one object to another.

One can use the symbol of (+) to present extra charge and the symbol of (-) to represent missing charge

Electrostatics and current flow are not two separate subjects. Knowledge of their relationship helps us to have a basic understanding of the current flow.

The concepts of electric field and electric potential cannot be applied instead of each other.

Nothing would happen when a charged object was brought close to a neutral object.

Rubbing a neutral rod with a neutral piece of cloth can result in them both becoming charged.

When a wood rod was placed between a charged material and an electroscope, the leaves inside the electroscope will not move apart because the wood rod is a nonconductor.

The electric force in which two charges apply to each other depends on the charges.
