## Coulomb’s Law – Electrostatic Force – Formula – Example

Coulomb’s Law – Electrostatic Force – Formula – Example. Learn how to calculate the electrostatic force between 2 electric charges using Coulomb’s Law.

## What’s Static Electricity? – Examples

Static electricity is static, since it is a current that is going nowhere. Both, DC and AC current flow in some direction, but static electricity does not.

## Electric Field – Lines of Force – Electric Field Unit

If a charge Q is affected by an electrostatic force, there is an electric field. If at some point the electric field is known, we can find the electrostatic force on a charge Q at that point

## Electricity and structure of matter

The matter is divided into molecules, which in turn are divided into atoms. These atoms are composed of two parts: nucleus and periphery.

## Positive and Negative Charges – (electrons, protons, neutrons)

If a body has more electrons than protons, it is negatively charged. If it has more protons than electrons it is positively charged

## What is an electric charge?

The electron (or proton, since they have the same charge) is the basic unit of electric charge. We can therefore consider the electron as the elementary unit of electric charge.

## Magnetic Field – Magnetic Field Lines

Magnets. Charges in motion (electric current) behave like magnets (produce magnetic fields)

## Polarization of a conducting material

If an electric field is close to a metallic body, part of it is positively charged and other part negatively charged

## First Right Hand Rule

The First Right-hand Rule or (Magnetic Force induced on a Current-Carrying Wire) says that if a current-carrying wire is in the presence of a magnetic field, a force is exerted on the wire.

## Second Right-Hand Rule – Electromagnetism

Second Right-Hand Rule. When a current flows through a conductive wire, a non-visible effect called the electromagnetic field is generated around it.
