A) Increases in the first circuit and decreases in the other
B) Increases in both the circuits
C) Decreases in both the circuits
D) Decreases in the first circuit and increases in the other
Correct Answer: D
Solution :
For the first circuit \[i=\frac{V}{Z}=\frac{V}{\sqrt{{{R}^{2}}+{{\omega }^{2}}{{L}^{2}}}}\] \[\therefore \] Increase in w will cause a decrease in i. For the second circuit \[i=\frac{V}{\sqrt{{{R}^{2}}+\frac{1}{{{\omega }^{2}}{{C}^{2}}}}}\] \[\therefore \]Increase in w will cause an increase in i.
