A) 1.6 V
B) 1.0 V
C) 1.2 V
D) 2.0 V
Correct Answer: C
Solution :
Equivalent resistance of the circuit \[{{R}_{eq}}=100\Omega \] current through the circuit \[i=\frac{2.4}{100}A\] P.D. across combination of voltmeter and 100 W resistance \[=\frac{2.4}{100}\times 50=1.2V\] Since the voltmeter and 100 W resistance are in parallel, so the voltmeter reads the same value i.e. 1.2V.
