Let us consider a shunt type ohmmeter which uses a 10mA basic dArsonval movement with an internal resistance 5. The battery voltage is 3V. It is desired to modify the circuit by adding an appropriate resistor Rsh across the movement, so that the instrument will indicate 0.5 at the midpoint scale. Calculate the value of shunt resistor, Rsh; (b) Value of the current limiting resistor R1.
