Frequently Asked Questions

Q1: What is electronics and what is the advantage of studying electronics?

A1: Electronics is one of the branches of engineering where one studies the control and flow of electrons in different medium. Electronic devices, their utilization are studied in this branch.

Advantages of studying electronics is that one may apply the knowledge in computers, ATM, Mobile phones, Television, digital camera, pen drive etc.

Q2: What are the characteristics of AC waveform?

A2: Characteristics of AC waveform are,

  • Period (T) – Length of the time (in seconds) taken by the waveform to repeat itself from beginning to end.
  • Frequency (f) – Number of time the waveform is repeated within a one second time period
  • Amplitude (A) – Intensity of the magnitude of the waveform signal is measures in amps or volts

Q3:  What is extrinsic material?

A3: Extrinsic material is a semiconductor material which has been subjected to the process of doping.
