PhysicsMoving Charges and MagnetismJEE Advanced 2019

Two identical moving coil galvanometers have 10 resistance and full scale deflection at 2 A current. One of them is converted into a voltmeter of 100 mV full scale reading and the other into an Ammeter of 1mA full scale current using appropriate resistors. These are then used to measure the voltage and current in the Ohm's law experiment with resistor by using an ideal cell. Which of the following statement(s) is/are correct?

Answer: (B),(C)

Solution

Voltmeter: total resistance : (A) wrong. Ammeter: shunt , and the ammeter resistance (shunt in parallel with 10 ) :
