Resistance of a metallic conductor is given by ___________(a) R = ^I�

1.	Resistance of a metallic conductor is given by ___________(a) R = ^I⁄A(b) R = ^ρ⁄A(c) R = ^ρl⁄A(d) R = ^1⁄AThis question was addressed to me by my school principal while I was bunking the class.This key question is from Transducer Selection Factors in portion Transducers of Electrical Measurements
Answer» Correct CHOICE is (c) R = ^ρl⁄A Easy explanation: The resistance of a metallic conductor is given by the relation R = ^ρl⁄A where, R is the resistance l is the length A is the AREA of cross-section ρ is the resistivity of MATERIAL of the conductor.
