If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
What is swamp resistor?
Resistor placed in the emitter lead of a transistor circuit to minimize the effects of temperature on the emitter-base junction resistance.
Is a Resistor a nonlinear device?
It is a linear device if it is not a wire wound resistor. These become non linear to AC at high frequencies because of their inherent inductance.
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
The voltage drop in each resistance is?
V=IR by ohms law. Voltage across the resistor is the product of current flowing and resistance of the conductor at constant temperature.
Is there any change in resistance of carbon composition resistor due to change in temperature?
yes, calculate it from temperature coefficient of resistance.
What is thermistorhow is it works?
A thermistor is a temperature sensitive resistor, there are two types: 1) If the temperature rise the resistance will go higher 2) If the temperature rise the resistance will go lower

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.
Is a Resistor a nonlinear device?
It is a linear device if it is not a wire wound resistor. These become non linear to AC at high frequencies because of their inherent inductance.

Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
What is the relationship between Wattage and resistance of resistor?
There is no direct relationship.Power ('wattage') is a measure of the rate at which the resistor can dissipate energy; excessive power means that a resistor cannot dissipate energy fast enough to prevent its temperature becoming excessive -excessive enough to damage the resistor.As the rate at which a resistor can dissipate energy is determined by its physical size, a resistor's power rating(maximum continuous power it can handle without exceeding its rated temperature) depends on the physical size of the resistor.On the other hand, the resistance of a resistor is notaffected by its physical dimensions, as a resistor can be manufactured to any particular value of resistance for whatever physical size is necessary to achieve its rated power.If you know a resistor's rated power and its resistance, then you can calculate the maximum continuous current that resistor can handle without overheating (using the equation: power = current squared x resistance).
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
The voltage drop in each resistance is?
V=IR by ohms law. Voltage across the resistor is the product of current flowing and resistance of the conductor at constant temperature.
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.
Is resistor measured in amps?
No, a resistor isn't measured at all. A resistor has a quality called "resistance" - and that value is measured. Resistance is measured in Ohms.
