Ohms Law Tutorial and Power in Electrical Circuits
WebbJoule heating, also called Joule’s law, in electricity, the conversion of electric energy into heat energy by the resistance in a circuit. The English physicist James Prescott Joule discovered in 1840 that the amount of heat per second that develops in a wire carrying a current is proportional to the electrical resistance of the wire and the square of the current. WebbCharacteristics of PTC Thermistors. Silistors have a linear resistance-temperature characteristic, with a slope that is relatively small through most of their operational range. They may exhibit a negative temperature coefficient at temperatures above 150 °C. Silistors have temperature coefficients of resistance of about 0.7 to 0.8% / °C.
