Electro Magnetic Induction And Alternating Currents Question 156

Question: If we increase the driving frequency in a circuit with a purely capacitive load, then

Options:

A) amplitude $ V_{C} $ increases

B) amplitude $ V_{C} $ decreases

C) amplitude $ i_{C} $ increases

D) amplitude $ i_{C} $ decreases

Show Answer

Answer:

Correct Answer: C

Solution:

  • As $ X_{C}=\frac{1}{\omega C} $ ,

so with the increase in frequency, $ X_{C} $

decreases and so $ i_{C} $ increases.
