The coil of a galvanometer is `0*02xx0*8m^2`. It consists of `200` turns of the wire and is in a magnetic field of `0*20T`. The restoring torque constant of suspension fibre is `10^-6Nm//degree`. Assuming magnetic field to be radial (a) What is the maximum current that can be measured by this galvanometer if scale can accommodate `45^@`deflection? (b) What is the smallest current that can be detected if minimum observed deflection is `0*1 degree`?
