calculate the resistance of a copper wire of length 2 metre in India of cross section 10 to the power minus 6 metre square is resistivity of copper 1.7 into 10 to the power minus 8 ohm metre |

Answer» Answer: Given, Length = 2m Area of cross section = 10^-6 sq. m Resistivity = 1.7 × 10^-8ohm.m Now, R = p×l/A R =( 1.7 × 10^-8) × 2/10^-6 R = 3.4 × 10^-8/ 10^-6 R = 3.4 × 10 ^-8-(-6) R = 3.4 × 10^-8+6 R = 3.4 × 10^-2 R = 0.034 OHM.PLEASE MARK ME THE BRANILIEST ☺ THANK YOU |
