WebThe power rating of a resistor defines the maximum energy a resistor can safely dissipate. As stated by Joule’s first law, the generated electrical power is the product of the voltage ( V) across the resistor and the current ( I) flowing through the resistor: P = V ⋅I P = V · I. When the electrical power equals the dissipated heat (by ... WebA 5-band resistor is more precise than a 4-band type because of the inclusion of a third significant digit. A 6-band resistor is like a 5-band resistor but includes a temperature coefficient band (the 6th band). Below (Table 1), you can see an overview of the different band types. Table 1. An overview of the different bands in a resistor.
