భావన:

\({R_{sh}} = \frac{{{R_m}}}{{M - 1\;}}\)

ఇక్కడ,

Rsh = షంట్ నిరోధకత

Rm = మీటర్ నిరోధకత

M = గుణ కారణాంకం

M = (విద్యుత్ విలువ)/(ముందుగా ఉన్న విలువ)

లెక్కింపు:

\(M = \;\frac{{100 \times {{10}^{ - 3}}}}{{60 \times {{10}^{ - 6}}}} = 1666.67\;\)

\({R_{sh}} = \frac{{100}}{{1666.67 - 1\;}} = \frac{{100}}{{1665.67}} = 0.06\;{\rm{\Omega }}\)

ఇప్పుడు 2వ వలయం విద్యుత్ విభజన నియమాన్ని వర్తింపజేయడం ద్వారా, మనం పొందుతాము

\({I_{sh}} = \frac{{100 \times {{10}^{ - 3}} \times 100}}{{100.06}} = 99.9\;mA\)
