24. A transformer has a core loss of 160 watts when its primary is connected to a 230- volt 60-cycle source. When the transformer is served by a 40-cycle supply, the impressed voltage is reduced to 4%o of 230 volts, or 153 volts, to maiatain the Bame flux density as on 60 cycles; under this condition the core loss was found to be 96 watts. Calculate the 60-cycle hysteresis and eddy-current loases.

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.
