The resistance RG of the coil of a pivoted-coil galvanometer is `9.36 Omega` and a current of `0.0224 A` causes it to deflected full scale. We want to convert this galvanometer to an anuneter reading 20.0 A full scale. The only shunt available has a resistance of `0.0250 Omega`. What resistance R must be connected in series with the coil of galvanometer ?
