Which of the following statements about parallel plate capacitors is/are correct? I. Capacitance of the capacitor is inversely proportional to the distance between the plates II. Capacitors can filter a.c signals from d.c III. Capacitors can store charges
A. I only B. I and II only C. II and III only D. I, II and III
Correct Answer: C
Explanation
Capacitors pass AC but block DC signals (when charged up to the applied DC voltage), they are often used to separate the AC and DC components of a signal. Capacitors are also primarily used to store energy.
