How do you get input impedance and output impedence of op amp?
Scroll down to related links and look at "Measurement of input impedance and output impedance".
A 480-volt circuit has an impedace of 60 ohms what is the current?
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
What is the combination of winding losses and self induction is referred to as?
Impedence
What is impedance inversion?
A device "GYRATOR" which is used in ICs instead of inductor and capacitor due to small in size ,when we put capacitor in o/p output of gyrator then it gives inductor characterstics on i/p and vice-versa.This phenomenon is called impedence inversion.
What is the impedence?
Impedance is the complex form of resistance. Impedance takes into account capacitance and inductance in a circuit as well. Impedance can be represented as resistance as a function of frequency.See link.AnswerImpedance is not a 'complex form of resistance'. It is the vector sum of a circuit's resistance and reactance. In electrical engineering, 'resistance' has a very specific meaning, and cannot be used to denote 'opposition'.
What is the function of a buffer amplifier in electronics?
A buffer amplifier can be used to transform high input impedence to low output impedence, or vice-versa.
How do you get input impedance and output impedence of op amp?
Scroll down to related links and look at "Measurement of input impedance and output impedance".
Why output impedence is high in opamp?
Output impedance in an op-amp is not high - it is low - input impendance is high, and this is because the input stage transistors have high gain.
Could you briefly explain the applications of FET?
Due to its *low noise *high input impedence and low output impedence FET is used in numerous applications. *Buffer ampliier *Phase shift oscillator *Integrator *Amplifier
Why output impedence should be low?
Never heard the word "impedence".To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
What happens if a high impedence amplifier is connected to a low impedence speaker?
Scroll down to related links and look at "Interconnection of two units" and find the picture of the amplifier and the loudspeaker. Learn about "voltage bridging" - Zout < Zin. There are no power amplifiers with a high impedance output.
Why CB amplifier preferred for high frequency than CE amplifier?
1)in cc configuration we use to get the low output impedence where as in ce we use to get the high output impedence. 2)in cc amplifier we use to have the voltage gain equal to unity where as in ce amplifier we use to have the high voltage gain. 3)in cc amplifier there is high power gai which is used for impedence matching where as in ce amplifier due to the high voltage gain the impedence matching is less impossible.
The definition of the term 'characteristics of a transistor'?
It can be used in 3 configurations, common emmiter, common base, common collector, in which common emitter is most widely used configuration.Its a 3 terminal device.It can be use as an amplifiersIt is use in all digital logic familiesHigh input impedence; low output impedence
Conditions for faithful amplification?
1. Signal to noise ratio should be low at the amplifier outlet. (Vaccuum tube amps are best.) 2. No distortion at the output due to the amp being overdriven. 3. Impedence matching at the input and output.
What happens if you connect 4 ohms impedance speakers which are 40 w RMS and 200w MAX to a 8 ohms and 30 w impedancece amplifier?
If the amplifier is not rated for 4 ohms impedence, you will quickly over-current the amp, burning out components. The power handling of the speaker and power output of the amplifier does not matter in this case. It must be compatible with the impedence load that you are connecting.
What is maximum power transfer theorem?
Max efficiency of energy transfer can only occur when impedence source matches the impedence of the load.
How do you get the power factor?
Resistance divided by impedence
