Answer:
resistance is also tripled
becomes 2/3R of actual resistance
Explanation:
R is directly proportional to length of the conductor.....so as length increases resistance also increases..so becomes three times
Radius=D/2
resistance is inversely proportional to radius..so D=2/resistance
3D=2/R
D=2/3R
I hope this helps you ☺️
