Thermistors

A thermistor is a special type of resistor whose resistance is more temperature-dependent than standard resistors. The resistance of the thermistor decreases with increasing temperature. This is the basic principle of thermistors. This allows the thermistor circuit to detect very small temperature changes that cannot be observed with the Resistance temperature detectors (RTDs) or the thermocouples. Since the resistance of a thermistor is temperature dependent, it can be connected to an electrical circuit to measure body temperature. This high sensitivity to temperature changes makes thermistors very useful for accurately controlling and calibrating temperature measurements. In general, resistance increases with increasing temperature in most metals, but thermistors react negatively.

2. Consider a Coaxial Cable that is made up of three regions. From 0<<a the cable is made
of a copper conductor with surface charge density +o. From a<r<b the cable is made of
empty space. From b<r<c the cable is made of a uniformly charged material with overall
density p.
a. First find and plot the electric field as a function of distance from -0 to r-c.
b. Second, find a value for p such that the coaxial cable has no external electric
field.
