What type of resistors are generally used when a high power rating is needed?
A) carbon film
B) metal glaze
C) wire-wound
D) metal film
Wire-Wound
A type of resistor or inductor where wire is wound around a core to create a specific electrical resistance or inductance value, often used for precision components.
Power Rating
The rating of a resistor that indicates the number of watts that can be permitted without damage to the device.
Carbon Film
A type of resistor where a film of carbon is deposited on an insulating substrate, used for its predictable resistance properties.

Final Answer :
C
Explanation :
Wire-wound resistors are generally used when a high power rating is needed because they can dissipate more power compared to other types of resistors like carbon film, metal glaze, or metal film. This is due to their construction, which involves winding a metal wire around a ceramic, plastic, or fiberglass core. This design allows for efficient heat dissipation.
