Electric Charges Basics

It surrounds every electric charge and exerts the force that causes other electric charges to be attracted or repelled.

• Magnetic Field

• Electric field

• Electromagnetic field

• charges

Charges can be positive, negative or neutral.

• True

• False

• Depend on the type of matter

Is a material through which electrons move easily and transform the energy in electrical energy without effort.

• Neutrons

• Insulators

• Charging by conduction

• Conductors

Is a material in which electrons are not able to move easily. They struggle to conduct electricity.

• charging by insulation

• insulators

• conductors

• protons

Glass, wood, plastic and rubber are example of:

• insulators

• conductors

• synthethic matter

• balance-charged particles

Iron, cobalt, gold and silver are examples of:

• balance-charged particles

• insulators

• conductors

• liquid elements of the periodic table

Is the process of transfering charge by touching or rubbing.

• Ohm's law

• Charging by contact

• Coulomb's law

• Charging by induction

When a nearby charged objects causes the rearrengement of electrons in th neutral object.

• Charging by induction

• Charging by contact

• Ohm's law

• Coulomb's law

predicts that the force exerted by one point charge on another is proportional to the product of the two charges.By changing one charge while keeping other things constant and seeing if the force is proportional to it.

• Ohm's law

• Coulomb's law

deals with the relationship between voltage and current in an ideal conductor. This relationship states that:

The potential difference (voltage) across an ideal conductor is proportional to the current through it.

The constant of proportionality is called the "resistance", R.
