Electronic Devices

A Short Note on Electronic Devices

Any device, in general, is intended to do some task. When we narrow down electronic devices or rather electronic components - they sort of behave in such way that they perform certain tasks in communication, information processing, signal processing. All these actually reflect in our daily life - when we use smartphones, ipods, laptops, when we make a skype call so on.

The combination of electronic components is the electronic circuits. Thus, electronic devices are the beginning point of all multi-functional gadgets we use. Understanding the behaviour of electronic devices will help us understand the functioning of the complex circuits.

Electronic components are widely classified as active, passive or electromechanical components. 

Active Components : 

• Diode
