      The reading of the ideal voltmeter in the adjoining diagram will be

    A)            4 V

    B)            8 V

    C)            12 V

    D)            14 V

    Correct Answer: B

    Solution :

               Current flowing in the circuit \[i=\frac{E}{R}=\frac{10-4}{20+10}=\frac{1}{5}A\] P.D. across AC \[=\frac{1}{5}\times 20=4V\] P.D. across AN = 4 + 4 = 8V
