Chapter 1 - Resistor Fundamentals What is the Power Rating of a Resistor? The power rating of a resistor defines the maximum energy a resistor can safely dissipate. As stated byJoule’s first law, the generated electrical power is the product of the voltage (V) across the resistor and the...
The power rating can be rated in watts or W and it is the units of power. Usually, if the resistor size is larger, then the resistor can handle more power. When the wattage of the resistor enhances then the cost will be increased. Generally, this rating ranges from 1/8th watt to kil...

Even if the formula for DC heat dissipation in a resistor isn't at your fingertips, a little Ohm's Law and the definition of power can easily create it. On the other hand, forgetting to calculate power ratings, particularly for cathode resistors and RC ripple filters, is one of the most...
必应词典为您提供nominal-power-rating-of-a-resistor的释义,网络释义: 电阻标称功率额定;电阻器的额定功率值;
The power rating should never be exceeded. • The power rating decreases with a rise in ambient temperature. The published power rating usually only applies with an ambient temperature of 20 C and decreases to zero at some temperature, depending on the materials used to fabricate the resistor....
