The resistance of a wire is \[{{10}^{-6}}\Omega \] per metre. It is bend in the form of a circle of diameter \[2\,m\]. A wire of the same material is connected across its diameter. The total resistance across its diameter AB will be

\[14\pi \times {{10}^{-6}}\Omega \]

\[\frac{4}{3}\pi \times {{10}^{-6}}\Omega \]

\[\frac{2}{3}\pi \times {{10}^{-6}}\Omega \]

\[0.88\times {{10}^{-6}}\Omega \]
