Two identical moving coil galvanometers have `10Omega` resistance and full scale deflection at `2muA` current. One of them is converted into a voltmeter of 100mA full scale reading and the other into an Ammeter of 1mA full scale current using appropriate resisters. These are then used to measure the voltage and current in the Ohm’s law experiment with `R=1000 Omega` resistor by using an ideal cell. Which of the following statement(s) is(are) correct?

Options

A. The resistance of the Voltmeter will be 100 `k Omega`
B. The resistance of the Ammeter will be 0.02 `Omega` (round off to `2^(nd)` decimal place)
C. The measured value of R will be `978 Omega lt R lt 982 Omega`
D. If the ideal cell is replaced by a cell having internal resistance of `5Omega` then the measured value of R will be more than 1000 `Omega`
