A) the bulb glows dimmer
B) the bulb glows brighter
C) total impedance of the circuit is unchanged
D) total impedance of the circuit increases
Correct Answer: B
Solution :
\[{{I}_{rms}}=\frac{{{V}_{rms}}}{\sqrt{{{R}^{2}}+{{\left( \frac{1}{\omega C} \right)}^{2}}}}\] As \[\omega \] increases, \[{{I}_{rms}}\] increases. Therefore the bulb glows brighter.You need to login to perform this action.
