Wheatstone bridge principle is used to measure the specific resistance \(\left(S_{1}\right)\) of given wire,having length \(L\), radius \(r\). If \(X\) is the resistance of wire, then specific resistance is; \({S_1} = X\left( {\frac{{\pi {r^2}}}{L}} \right).\)
If the length of the wire gets doubled then the value of specific resistance will be:
357059 A portion of length \(L\) is cut out of a conical solid wire. The two ends of this portion have circular cross-sections of \({r_1}\;\) and \({r_2}({r_1} > {r_2})\) radii. It is connected lengthwise to a circuit and a current \(I\) is flowing in it. The resistivity of the material of the wire \(\rho .\) Calculate the voltage developed across it.
