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 the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Which metal has no resistance?
99.99% silver is the best for no resistance.
Is the sum of the resistance in a parallel circuit always excessds the total resistance in a circuit?
Not sure what you mean. The equivalent (total) resistance in a parallel circuit is less than any individual resistance.
What happens to its resistance when an electrical device is heated?
That will depend on the temperature coefficient of resistance of the device, which could be positive (i.e. resistance increases with increasing temperature), negative (i.e. resistance decreases with increasing temperature), or zero (i.e. resistance is unaffected by temperature changes).
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.
Swamping resistor is made up of?
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.
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.

What is a swamping gun?
Ah! You have been reading the lyrics to Yankee Doodle Dandy! Swamping is an archaic term for large, great, huge- as in the reference to seeing a swamping gun on a wagon, a load for father's cattle- first time the writer had seen a cannon- on wheels, pulled by draft oxen. Truly, a big gun.
