One of the most familiar forms of energy is heat. When a current (I) is forced through a resistor (R) by applying a potential (V), the electrical energy is converted to heat energy as observed by the rise in temperature of the resistor. Remember that power is the rate at which energy is consumed. WebApart from the two distinct categories of NTC and PTC, thermistor types differ by curve and range. Overall, they are typically identified by their resistive capacity at 25℃. We’ve already briefly mentioned the common 10K thermistor, for example. It resists 10,000 ohms of current when the ambient temperature is 25℃. fifa 22 dream team maker
