Question

The resistance of the conductor is R. If its length is doubled, then its new resistance will be * 1 point R 2R f4R 8R

Answer 1

Answer:

2R

Explanation:

Resistance is directly proportional to increase in length.

Answer 2

Answer:

2R

Explanation:

if L becomes 2 L, R becomes 2 R.

R'  = ρ $\frac{2L}{A}$

So, R = 2R'.
