A moving coil instrument has a resistance of 70 Ω and gives full scale deflection of 100 scale divisions for a current of 1 mA. The instrument is connected in parallel with a shunt of 30 Ω resistance and this combination is then connected in series with a load and supply. Determine the current in the load when the instrument gives an indication of 80 scale divisions.

1.	A moving coil instrument has a resistance of 70 Ω and gives full scale deflection of 100 scale divisions for a current of 1 mA. The instrument is connected in parallel with a shunt of 30 Ω resistance and this combination is then connected in series with a load and supply. Determine the current in the load when the instrument gives an indication of 80 scale divisions.
A.	1 mA
B.	3.2 mA
C.	2.66 mA
D.	4 mA
Answer» D. 4 mA
