A) 6 W, 5 amp
B) 10 W, 0.1 amp
C) 4 W, 1.0 amp
D) 12 W, 0.5 amp
Correct Answer: C
Solution :
Resistance of the part AC \[{{R}_{AC}}=0.1\times 40=4\Omega \] and \[{{R}_{CB}}=0.1\times 60=6\Omega \] In balanced condition \[\frac{X}{6}=\frac{4}{6}\Rightarrow X=4\Omega \] Equivalent resistance \[{{R}_{eq}}=5\Omega \] so current drawn from battery \[i=\frac{5}{5}=1A\].You need to login to perform this action.
