Questions and Answers

What is a capacitor?

  • A single conductor used to store electrical energy
  • A system of two conductors separated by a conductor used to store electrical energy
  • A system of two insulators used to store electrical energy
  • A system of two conductors separated by an insulator used to store electrical energy (correct)

    • What is the charge of the capacitor?

  • The charge of the capacitor is directly proportional to the voltage
  • The two conductors have charges Q and ʹQ, where Q is called the charge of the capacitor (correct)
  • The charge of the capacitor depends on the size of the conductors
  • The total charge on the capacitor is always positive

    • What is capacitance?

  • The measure of voltage difference between the conductors of a capacitor
  • The measure of total charge stored in a capacitor
  • The ratio of charge to voltage for any electrical component
  • The ratio Q/V for a capacitor is constant and is called the capacitance (c) of the capacitor (correct)
