What is Electronics ?

Answer :

Questions : 1 :: What is the difference between a transistor and a thyristor?

Both a transistors and thyristor are semiconductor devices. But the main difference between then is that, a transistor has three layers of semiconductors, where as a the thyristor has four layers of...View answers

Questions : 2 :: Where are LVDT used?

The LVDT sensors are mainly used as a transfucer. Hence they are used in industries as a secondary transducers for servo machines.

Questions : 3 :: What is the difference between ideal voltage source and ideal current source


The main difference between the two is that, the ideal voltage source has zero internal resistance where as the ideal current source has infinite internal resistance.

Questions : 4 :: How does avalanche occur in a diode?

The avalanche breakdown occurs in a diode due to the breakdown voltage.

Questions : 5 :: What are Clipper and Clamper?

Clipper is a circuit which removes a part of the waveform, which can be either positive of negative, so that it doesn't exceed a certain voltage level. Clamper is a circuit that adds a DC...View answers

Questions : 6 :: What are AM and FM?


AM-Amplitude modulation is a type of modulation where the amplitude of the carrier signal is varied according to the information bearing signal. FM-Frequency modulation is a type of modulation where...View answers

Questions : 7 :: What is an amplifier?

An amplifier is an electronic device or an electrical circuit, which is used to boost the voltage, power or current of an applied signal.
