Question

A wire is cut into three equal parts. Calculate the resistivity of each part. ​

Answer 1

Answer:

If the inital resistance is R, each piece has resistance R/3. Connect 3 equal resistors in parallel and the total resistance is 1/3 of each separate resistor. So we end up with a total resistance of 1/3 of R/3 = R/9. So the resistance is 1/9 of the original wire's resistance
