Electronics Fundamentals

The fundamentals of electronics should be start with by learning about the basic components. the types of components are:

1)active components

2)passive components.

The electronic component is simply defined as it's a basic discrete device. and every electronic component have a number of electrical terminals or leads.

Active Components: 

The components usually used to inject the power into a circuit. Active components also includes amplifying components such as transistors , tunnel diodes, etc.

Diodes

transistors

Passive Components: 

The components which are can't introduce the energy in a circuit. i.e. it can't be acts as a source of power. Passive components includes the two terminal devices like resistors, capacitors, inductors.
