Question
Replacing a wire resistor with another of the same materialand length but with three times the diameter will have the effectof changing the resistance by what factor? Note: a factor of 5indicates an increase resulting in 5 times the original value; afactor of 1/5 indicates a decrease resulting in 1/5 times theoriginal value. A) 9 B) 3 C) 1/3 D) 1/9 E) 27 F) 1/27 G) none of the above. the correct answer is______________________ Replacing a wire resistor with another of the same materialand length but with three times the diameter will have the effectof changing the resistance by what factor?

The correct answer is D 1/9 which occurs because of the increase indiameter which changes the area. For an example, a smallerpipe slows the fluid moving. However, if the pipe is biggerthere is less resistance.
