Electronics is the branch of science that deals with the study of the flow and control of electrons, their behavior and effects in materials such as semi-conductors and with devices using electrons. It can be simply defined as; the movement of electrons through semiconductors or gases.

Electronics are used in making electronic devices. Examples of such devices are mobile phones, televisions, radios etc. There are components in the electronic devices found on the motherboard, these components on the motherboard are connected in many different ways to form electric circuits which are used in various ways.

Examples of these electronic components are:

• Capacitor


• Diode

• LED

• Resistor
