Question 39

Capacitors

A 5-V battery is connected across the plates of a 2.0μF uncharged parallel plate capacitor. The charge on the capacitor after a long time is

  1. A.2.5μC
  2. B.10.0μC
  3. C.20.0μC
  4. D.50.0μC
Show the answer and explanation

Answer: B (10.0μC)

Explanation

Q = CV = 2.0 μF × 5 V = 10.0 μC.
