Swamping resistor is mostly made of manganin or constantan because these materials have temperature coefficients very close to zero thus there is a very less change in the resistance of these materials with change in temperature.

Who made the first resistor?
Otis f.boykin made and invented first the resistor
What do you call the variable resistor when it is set up to alter the size of the voltage over the resistor?
A potentiometer.
What are resistors in IC made of?
Resistor in IC are made of semiconductor structures in a manner similar to transistors and PN junctions
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
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
What is swamping resistance?
(Electronics) Resistor placed in the emitter lead of a transistor circuit to minimize the effects of temperature on the emitter-base junction resistance and its resistance is called swamping resistance.
What is the purpose of the series resistor in your designed ammeter circuit?
You appear to be referring to a 'swamping resistor' which is connected in series with a moving-coil ammeter's moving coil.To minimise any errors due to temperature changes in the resistance of the instrument's moving coil, the coil is connected in series with what is termed a 'swamping resistor' whose resistance is large in comparison with that of the moving coil, and which is manufactured from an alloy with a very lowtemperature coefficient of resistance (i.e. a metal whose resistance is hardly effected by wide variations in temperature).For example, if the resistance of a 1-Ω moving coil increases to, say, 1.1 Ω, when its rated current flows through it, this will introduce a 10% error in the instrument's reading.But by calibrating the instrument with a series swamp resistor of, say, 49 Ω, the overall resistance at rated current will become 50.1 Ω. This will result in an error of just 0.2%.A swamping resistor, then, is an integral part of all moving-coil instruments and, when we refer to an instrument's 'coil resistance', we actually mean the combined resistance of the moving coil itself and its swamping resistor.
Which of the material is used for the swamping resistance that is connected in series with the working coil of a voltmeter?
A swamping resistor is usually manufactured from the metal alloy manganin (trade name), or other alloy with similar resistance/temperature characteristics -i.e. practically zero temperature coefficient of resistance. In other words, its resistance will remain more-or-less constant over a wide range of temperature variation.
Who made the first resistor?
Otis f.boykin made and invented first the resistor
Where is the resistor in an electric stove?
What is a electric stove resistor made
What should you do to avoid capsizing or swamping a boat?
Anchor from the bow rather than the stern to avoid capsizing or swamping a boat.
What is different between the resistor and pullup resistor?
A "pull-up" resistor is a resistor used to to perform a specific electronic function - it is not a different type of resistor. A very small current flows through a pull-up resistor so it does not need to be high wattage (1/8 watt is generally fine). The value of a pull-up resistor depends on the resistance of the sensor. If it is simply on or off (no resistance) then a typical pull-up resistor might be 10k ohms.
How does the filament in a light bulb work?
it is made of tungsten and is a resistor when current flows thru it it heats up and glows
Why does a resistor heat up when an electric current flows through it?
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
What should you do to avoid capitizing or swamping?
Anchor from the bow
