 Related Questions Latest Answer : There is no particular operating voltage for the operation of laser. Small voltage is enough to glow that laser, the principle of laser is the excitation of atoms from lower state to higher state. For playing purpose of laser the desired ... Read Answers (1) | Asked by : maharajan.k Latest Answer : In any (electronic) device controlling parameter is current it is called current controlled device. eg bilpolar transistor- output current is a function of base current. In any (electronic) device controlling parameter is voltage it is called voltage ... Read Answers (1) | Asked by : rangan What is power electronics? Latest Answer : Power electronics is the general branch of electronic design that involves handling, converting or conditioning relatively high power. ... What is the difference between Power Amplifier and Voltage Amplifier? Latest Answer : Power amplifiers basically amplify both current and voltage (p=v*i).Voltage amplifiers only amplify the voltage. ... Why BJT is known as current controlled device and FET is known as voltage controlled device? Latest Answer : BJT as current controlled device - Base current controls the collector an emitter currentsFET as voltage controlled device-Field of p or n region decides width of conducting channel in n type or p type FET ... How to calculate knee point voltage? Describe its purpose for differential protection. The output of the rectifier pulsating in nature, it consists of a desired DC component of voltage and unwanted ripple components. These ripple components are removed by placing filter circuit at the output Latest Answer : Filters are used to remove the unwanted or undesirable components of a output
waveform, so the basic work of filters is to smoothen the output.From electrical devices we
are not getting perfect sinusoidal output, it contains a DC component i.e.
ripples, ... Why FET is known as voltage control device? Latest Answer : Since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as voltage controlled device.For example: In a MOSFET, the current from drain to source depends upon the width of the depletion ...
