A wire of length 100 cm has a resistance of 10\(\Omega\). If its cross-sectional area is 0.005cm2, determine its resistivity
A
0.0005\(\Omega\)cm
B
0.0015\(\Omega\)cm
C
0.0016\(\Omega\)cm
D
0.0700\(\Omega\)cm
Verified Correct Answer: A.
Physical Principles & Numerical Solution
e = \(\frac{RA}{L} = \frac{10 \times 0.005}{100} = 0.0005\)
