Concept explainers

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.

If the load is connected to the generator thgrough an inductive line and the voltage at the load side is the same as the voltage at the terminals of the generator, which of the following must be true? O A. The reactive power is flowing from the generator to the load and from load to the generator at the same time. O B. The load is disconnected, and no power is delivered to the load. O C. The load has a poor power factor and it's absorbing too much reactive power. O D. None of the other choices are correct O E. The generator is unable to produce reactive power; therefore, the reactive power is flowing from the load to the generator.
