A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor.Thermistors are widely used as inrush current limiter, temperature sensors (NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements.ver small changes in temperature, if the right semiconductor is used, the resistance of the material is linearly proportional to the temperature. There are many different semiconducting thermistors with a range from about 0.01 kelvin to 2,000 kelvins (â273.14 Â°C to 1,700 Â°C) .
A refractive error, or refraction error, is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity.The number of people globally with refractive errors has been estimated from 800 million to 2.3 billion. Hyperopia: When the optics are too weak for the length of the eyeball, one has hyperopia or farsightedness. 2  This can arise from a cornea or crystalline lens with not enough curvature (refractive hyperopia) or an eyeball that is too short (axial hyperopia).
