dentify the correct statement(s) among the following:
(A) An electric bulb connected with a capacitor in series with electric DC source, glows with full brightness.
(B) An electric bulb connected with capacitor in series with an AC source, does not glow.
(C) An electric bulb connected with capacitor in series with a electric DC source, does not glow.
(D) An electric bulb connected with capacitor in series with an AC source, glows well.
Choose the correct answer from the options given below:
- A (A) only
- B (A) and (B)
- C (B) and (C)
- D (C) and (D) only
Answer & Solution
Correct Answer
(D) (C) and (D) only
Step-by-step Solution
Detailed explanation
Capacitor blocks DC current when fully charged; thus, bulb does not glow. Statement (C) is correct. Capacitor allows AC current to flow due to capacitive reactance; thus, bulb glows. Statement (D) is correct. Therefore, (C) and (D) only.
