What are the typical power ratings for carbon-composition resistors?

Carbon-composition resistors are known for their common usage in a variety of electronic applications, particularly in circuits that require reliability and a degree of stability in resistance values. The typical power ratings for these resistors are generally in the range of 1/4 to 2 watts. This range is practical for many electronic applications where low to moderate power handling is required, and it aligns with their physical construction and thermal characteristics.

Within this power range, carbon-composition resistors can effectively dissipate heat generated from electrical current without risk of failure or damage under normal operating conditions. This characteristic allows them to be used effectively in everyday electronic devices and applications. Higher power ratings, as may be suggested by the other options, are generally more suitable for different types of resistors designed specifically for higher power applications, such as wire-wound or metal film resistors. Thus, the specified range of 1/4 to 2 watts reflects the appropriate selection for carbon-composition resistors in typical usage scenarios.
