Question on: WAEC Physics - 2014
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
Ask EduPadi AI for a detailed answer
Correct Option: A
e = (\frac{RA}{L} = \frac{10 \times 0.005}{100} = 0.0005)
