Question:
The regulator of an electrical fan is wound with:
The regulator of an electrical fan is wound with:
Show Hint
Eureka wire is preferred for fan regulators because of its high resistance and durability.
Updated On: Apr 21, 2025
- Nichrome wire
- Eureka wire
- Tungsten wire
- Carbon wires
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The regulator of an electrical fan is typically wound with Eureka wire, which is an alloy of copper and nickel. This material has high resistance and is ideal for controlling the current.
