Question:medium
If the length of a linear conductor is doubled and its area of cross section halved, its resistance is
If the length of a linear conductor is doubled and its area of cross section halved, its resistance is
Show Hint
Increasing length increases resistance, and decreasing area also increases resistance. Since both changes act in the same direction, you should expect a significant increase. Doubling length (\(\times 2\)) and halving area (\(\times 2\)) gives a total factor of 4.
