Default Is the wattage linear on a wirewound adjustible resistor?

Another thing to keep in mind, wire wound resistors have inductance.
Although probably not enough to become a substantial issue at audio
frequencies.



** Typical hollow, ceramic WW resistors rated at 100W show no change in value until the frequency is well over 100kHz.

The metal encased sort that need a heatsink show much less.

Inductance in WW resistors sometimes becomes an issue with very low values - like 0.1 ohms.
