hi does anyone know how do i draw a circuit that will convert a galvanometer with a full-scale deflection (f.s.d.) of 1mA and internal resistance of 20Ω into an instrument capable ofmeasuring up to 1A.and another circuit to convert the same galvanometer to read 10 volts f.s.d.

For the second, place a resistor in series, so that a voltage of 10V drives a current if 1mA.
