When current I flows through a wire, the drift velocity of the electrons is v. When current 2I flows through another wire of the same material having double the length and area of cross-section, the drift velocity of the electrons will be |
| Answer» SOLUTION :`v_(d)=(I)/(nAe), v_(d)^(.)=(2I)/((2A)N e)=v_(d)` | |
