Question 6

Capacitors

The plates of a 0.5μF uncharged capacitor are connected to a 10V battery. The charge on the capacitor after a long time is

  1. A.20.0μC
  2. B.50.0μC
  3. C.10.0μC
  4. D.5.0μC.
Show the answer and explanation

Answer: D (5.0μC.)

Explanation

When fully charged, Q = CV = 0.5 μF × 10 V = 5.0 μC.
