The winding resistance of a coil can be increased by
Answers
The winding resistance of a coil can be increased by increasing the number of turns in the coil or using thinner wires for winding.it is because the voltage is increased by doing this and current remains constant due to which the resistance increases.
Options are not provided in the question. The complete question is as following:
The winding resistance of a coil can be increased by
A. Increasing the number of turns
B. Using a thinner wire
C. Changing the core material
D. Increasing the number of turns or using thinner wire
Answer:
Low coils generally heat up faster and can cause short circuit.
Explanation:
More number of turns and use of thin wires can increase the winding resistance of a coil.
Increase in number of coil will increase the resistance which in turn produces less power and less current and prevent the short circuit.
Thin wire is used to increase resistance because a thin wire allows less number of electrons to carry the current.
Hence, the correct option is D.
