A degaussing circuit using a PTC thermistor is simple, reliable (for its simplicity), and inexpensive. As heaters, in the automotive industry, to provide cabin heating (in addition to heating provided by a heat pump or the waste heat of an internal combustion engine), or to heat diesel fuel in cold conditions before engine injection.
The Steinhart–Hart equation is a model relating the varying electrical resistance of a semiconductor to its varying temperatures.The equation is = + + (), where is the temperature (in kelvins),
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
Such relationship may take the form of a graph, where numerical values of a circuit variable are plotted versus frequency or component value (the most common example would be a plot of the magnitude of a transfer function vs. frequency). Symbolic circuit analysis is concerned with obtaining those relationships in symbolic form, i.e., in the ...
The temperature coefficient of a PTC heating element generally is a function of temperature. The Steinhart–Hart equation is often used to approximate this function. In some applications where the heater is used only in a narrow temperature range, a simple linear equation may be adequate.
A Connecticut man who allegedly killed a woman and her infant son in November targeted the woman because she owed him $400 for renting a vehicle of his, arrest reports said on Monday.
But the New Orleans-based 5th U.S. Circuit Court of Appeals in March found that the disputed warnings were "factual and uncontroversial," thus satisfying the relevant legal standard under the ...
