Topic: Electric Energy
Introduction
Electrical energy plays a dominant role in the economic and social development of nations. It is extensively used in industries, offices and homes for carrying out numerous essential operations. Electrical energy provides a reliable, pollution free energy option for both domestic and industrial purposes.[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”]
Concept of Electron Flow
Electrons are tiny negatively charged particles that are found in the atom. The electron moves freely inside the atoms of electrical conductors such as metals. Electrons are invisible to the eye but the effect of their movement can be seen and even measured in every electrical circuit. It is the flow of electrons that produce the flow of electric current
One of the conditions for obtaining electric current is the provision of potential difference between two points. If two such points with a difference in potential are joined together with a metallic conductor such as wire, electrons flow from the low potential point to the higher potential point, whereas electric current would flow from the high potential to the low potential point.
The diagram shows the flow of electrons and current in a closed circuit
Series and Parallel Circuits
The two major ways of connecting electrical circuits are in series or in parallel. In series circuit, circuit elements are joined end to end so that the same current flows through each circuit element in turn, while the potential difference across elements will differ.
