Question on: JAMB Physics - 2014
If a metal wire 4m long and cross-sectional area 0.8 mm2 has a resistance of 60, find the resistivity of the wire
A
5.3x10-7
B
3.0x10-5
C
1.2x10-6
D
3.2x10-6
Ask EduPadi AI for a detailed answer
Correct Option: C
\(P = \frac{Ra}{L}\Omega m\)
\(P = \frac{6 \times 0.8}{4}\Omega m\)
\(P = 1.2 \times 10^{-6}\Omega m\)
\(P = \frac{6 \times 0.8}{4}\Omega m\)
\(P = 1.2 \times 10^{-6}\Omega m\)
