Why is it simpler to plot the log of the resistance of the copper coil against temperature rather than the resistance against temperature?

It is quite simpler to plot the log of the resistance of thermistor against temperature. If you need to straighten out a curve in a graphical plot of two parameters, particularly if one axis covers a wide range that avoids all of your data appearing on one sheet of paper, then log the wide ranging variable.

What is the relationship between temperature and resistance for a thermistor?

With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases.

Why does the resistance of a thermistor decrease with temperature?

NTC thermistors, resistance decreases as temperature rises due to an increase in conduction electrons bumped up by thermal agitation from valency band.

How does current and resistance change with temperature in a thermistor?

The thermistor Their resistance decreases as the temperature increases. At low temperatures, the resistance of a thermistor is high, and little current can flow through them. At high temperatures, the resistance of a thermistor is low, and more current can flow through them.

Are resistivity and resistance the same?

The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity. The resistivity is a characteristic of the material used to fabricate a wire or other electrical component, whereas the resistance is a characteristic of the wire or component.

Why resistance decreases with increase in temperature in semiconductor?

When temperature is increased in case of a semiconductor the free electron gets more energy to cross the energy gap to the conduction band from the valence band.so now more electrons can go easily to the conduction band so resistance decreases with temperature.

Why does resistance decrease as light intensity increases?

The light energy produces more free electrons which increases the current for a certain voltage across the LDR which means a drop in resistance. The increasing temperature produces more free electrons and so the resistance falls.

How does temperature affect the resistance?

The effect of temperature on the resistance of the conductor is directly proportional to each other. The increase in temperature of the conductor increases its resistance and makes it difficult to flow current through it. Hence the increase in the temperature of the conductor increases resistance in the conductor.

Why is temperature a factor that affects the resistance of a material?

The resistance of conductors increases with an increase in temperature. This is due to an increase in the number of collisions of electrons with themselves and with the atoms of the metals.

Does resistance increase with temperature?

Heating a metal conductor makes it more difficult for electricity to flow through it. These collisions cause resistance and generate heat. Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance.
