A silver is screen printed on a ceramic substrate in such a way that the length

$($L$)$ of the trace is $1$ cm $,$ width $($W$)$ is $0\mathrm{.}2$ cm and the thickness $($d$)$ is $0\mathrm{.}5m.$ Find

the equivalent resistance of the print as shown in figure $4b,$ if the resistivity of

silver is $1\mathrm{.}724{10}^{-8}m.$
