Practicing Success
A piece of wire is cut into four equal parts and the pieces are bundled together side by side to form a thicker wire. Compared with that of the original wire, the resistance of the bundle is |

1/16 |
$ \text{Let resistance of original wire is R}$ $ \text{Resistance of one part of the wire is R/4}$ $ \text{When these are connected in parallel then } R'= \frac{R}{16}$ |
