Resistors are identified as to wattage by:?
(a) size
(b) color code
(c) types of materials
(d) internal construction
回答 (2)
a is probably the best answer. Any heat generated must be dissipated, and the amount of heat that can be dissipated is a direct function of the device surface area. Varies materials and internal construction may allow the resistor to operate at slightly higher temperatures without damage, but these would be secondary.
