The current flowing through a resistance causes a reduction of the voltage: current times voltage is power, in this case the thermal capacity that is allocated to oporniku, heating it. As a rule, the phenomenon is a nuisance electronics, as the heat must be appropriately carried out. The phenomenon is, however, also has its field of application heating resistors. These elements work as small heaters. The resistor strip is easy to install in the device, as performed on samoprzylepnym surface.
Generally, in electronic devices heat is not too desirable but there are situations when a simple thermoelectric heater heating element can solve many problems. The elements of this type is often used for the temperature stabilization of precision electronic components such as quartz oscillators or voltage reference. They work all the time, in a stable temperature.
In our store available different heating resistors. Such resistance heaters are characterized by two parameters - the resistance (electric resistance), as well as maximum power. The electrical resistance of the object, measure its resistance in relation to the flow of electric current. The opposite number is the electrical conductivity and the ease with which electric current flows. Electrical resistance has some similarity of the concept with the notion of mechanical friction. The unit of electrical resistance, SI is the Ohm (?). If you divide the voltage indicated on the resistor by using this option, wyliczymy which the current flows through the resistor panel. Current times voltage is power, which it is allocated.
We have the resistors of the strip, characterized by different maximum power electric. It determines the maximum heat output of this element and at the same time, the maximum power that can safely be lost in this oporniku. This affects the maximum voltage that can be applied to the heating resistor. Power (P) is equal to ilorazowi of the square of the voltage (U) and resistance (R) - P U2/R. for example, for a resistance of 2.4? and 12 V on oporniku will allocate 60 watts.
Thanks to its compact dimensions, especially thickness of 1 mm, the resistor strips are ideal as heating resistors for applications that require small size. The resistors are ideal, for example, for heating the enclosure, as well as a heater that tops 3D printers.
