Basic Properties of Matter and Electric Charges

Electrons are fundamental to the flow of electric current, representing the basic property of matter that allows for conductivity and electrical interactions.
Two basic types of electric charges exist: positive and negative. Positive charges are typically associated with protons, while negative charges correspond to electrons.

Net Charge in Atoms

A net negative charge in an atom arises when there are more electrons than protons, leading to an overall excess of negative charge.

Structure of Atoms

The nucleus of an atom is positively charged due to the presence of protons, while the surrounding electron cloud is composed of negatively charged electrons.

Electric Charge and Electron Flow

The flow of electrons constitutes negative electric charge, which is the form of electric charge commonly associated with electrical currents.

Electric Current Composition

An electric current is constituted by the movement of electrons through a conductor, allowing for energy transfer and power in circuits.

Direction of Electric Charge Flow

Electric charges flow in a circuit from the negative terminal to the positive terminal, which is opposite to the conventional current direction that assumes positive charge flow.

Function of Electric Circuits

The primary function of an electric circuit is to provide a closed path for electric current, facilitating the transfer of electrical energy for various applications.

Water Flow Analogy

The flow of electric current is analogous to the flow of water; both involve movement through a medium (conductors for electricity, pipes for water) and can demonstrate pressure differences (voltage for electricity, water pressure for flow).

Attribution of Electric Current Flow

The flow of electric current in a circuit is primarily attributed to the movement of free electrons in conductive materials, which allows for efficient energy transfer.
