Question

An a.c. source is connected to a capacitor 'C'. Due to increase in its operating frequency

• A. capacitive reactance increases.
• B. capacitive reactance remains constant.
• C. peak current increases.
• D. peak current decreases.

Hint:

Capacitive reactance falls as frequency rises, so the peak current rises.

Answer 1

The Correct Option is C

Step 1: Compare the options
Option A is wrong because $X_C$ decreases, and option B is wrong because it is not constant.

Step 2: Peak current
The peak current grows in direct proportion to $f$.

Step 3: Conclusion
So option C is correct and D is its opposite.

Final Answer:
The peak current becomes larger. \[ \boxed{\text{(C) }\text{peak current increases.}} \]
