    The ammeter A reads 2 A and the voltmeter V reads 20 V.  the value of resistance R is (Assuming finite resistance's of ammeter and voltmeter)                [JIPMER 1999; MP PMT 2004]

    A)         Exactly 10 ohm

    B)         Less than 10 ohm

    C)         More than 10 ohm     

    D)         We cannot definitely say

    Correct Answer: C

    Solution :

                                             \[2R>20\Rightarrow R>10\Omega \].
