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.

How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
What is the output impedance of common source amplifier circuit?
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
What is effect of an unbypassed resistor on the common emitter amplifier circuit?
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
What is scaling effect of feed back resistor on operational amplifier?
The scaling effect of a feedback resistor in an operational amplifier (op-amp) circuit influences the gain and output voltage response. Specifically, the feedback resistor, in conjunction with the input resistor, sets the closed-loop gain according to the formula ( \text{Gain} = 1 + \frac{R_f}{R_{in}} ) for a non-inverting amplifier. By varying the feedback resistor, the gain can be adjusted, allowing for precise control of the amplifier's output relative to its input. This scaling effect is critical in applications where specific amplification levels are required.
Can you use a 91ohm resistor in place of 100ohm resistor?
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.

Why capacitor reduce gain of ce amplifier?
Where is this capacitor in the circuit?A capacitor across the emitter bias resistor actually increases the AC gain because it bypasses that resistor, by increasing the ratio of collector impedance to emitter impedance which determines the amplifier voltage gain.A capacitor across the base input resistor actually increases the AC gain because it bypasses that resistor, by decreasing the attenuation of the input signal by the input circuit network.
How do you use RF and rrf in Rs calculation?
In the context of calculating resistance (Rs) in a circuit, RF (feedback resistor) and RRF (reference resistor) can be used in feedback amplifier configurations. RF is typically connected in the feedback path between the output and the inverting input of an operational amplifier, while RRF is used to set the gain of the amplifier. The relationship between these resistors can determine the overall gain of the circuit, which in turn affects the voltage drop and thus the calculation of Rs. By applying Ohm's law and the principles of feedback, you can derive Rs based on the values of RF and RRF in the circuit.
