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.
