if all resistance are not equal then we will get sum of voltages which are multiply by some constant.
e.g suppose we want to add v1 and v2 if all resister are not equal we will get output which is equal to k1v1+k2v2 where k1 and k2 are cinstant.

How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
Why you need RC coupled amplifier?
Rc coupled amplifier is used where good frequency response required. in case of multistage amplification system,To prevent resistance of one stage to come in parallel with next stage, it is used. we use capacitor as a coupling element between two consecutive stages.
Which amplifier converts millivolt to volt?
to convert a 100mv to 1volt u will have to multiply it by 10. so u will need a stepup amplifier to do that. u can depend on am op-amp based amplifier to do it if u r allowed to use external supply, else u will need a transformer for the same. Ashish.K
Use Ohm's Law and explain how 2 circuits have the same current but different resistance?
As we know V=IR, by changing the voltages in the two different circuits, we can maintain the same current even we have different resistance.
Why you use resistor in amplifier circuit?
Resistors come under passive electronic components and are extensively used in electronic circuits. So important are these components that it may be virtually impossible to build an amplifier circuit without involving resistors. Basically the function of a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance.
Reason use an op amp in a closed loop control system?
Differential Amplifier or Summing Amplifier are usually used in a closed loop control system. The error signal will be the DIFFERENCE between the setpoint value and feedback value for Differential Amplifier. Whereas for Summing Amplifier, the error signal will be the difference between the setpoint value and feedback value only if one of the value is inverted in polarity. Another reason Op Amp is used: amplify the error signal as error signals are usually very small. Hope this helps.
How can you use 'summing up' in a sentence?
Yes, I'll be summing up soon.
How do you increase the imput impedance of instrumentation amplifier?
Use a series resistance at the input. A problem could be that the amplification goes down.
The use of swamping resistor in differential amplifier?
the use of swamping resisters in amplifier is in order to protect the amplifier from high temperatures
You will have signal degradation unless you use the amplifier.?
You will have signal degradation unless you use the amplifier.

How to use the Line out in fender performer 650?
In order to use the line out in the Fender Performer 650, you will need an amplifier. Connect the cable from the line out to the amplifier. Make sure that the amplifier is turned on.
Is a 4 ohm subwoofer better then a 8 ohm subwoofer?
You need to match the speaker with the amplifier. Better or worse is not the question. The question is dynamic range and the possibility of overloading the amplifier. If the amplifier is rated 4 ohms, use a 4 ohm speaker. Same for 8 ohms. Do not "mix and match".
Which amplifier converts millivolt to volt?

If you have a sub woofer do you need an amplifier?
There are two types of subwoofers. 1. Active subwoofers 2. Passive subwoofers An active subwoofer will have a built-in amplifier. A passive subwoofer doesn't have a built-in amplifier which will require the use of an amplifier, the use of a power source.
When using two 8 ohm speakers with a terminal of 8 ohm should you use parallel or series wiring?
They should be in parallel so that both speakers will (a) get the full damping effect of the low amplifier output resistance, and (b) receive the maximum available voltage swing from the amplifier before limiting and distortion occur. If they sound the same in series, that cancels the effect of 40 years of 'techno' articles on speakers in glossy audio magazines :).
