Questions and Answers

Which type of current has a consistently flowing direction of electron flow in a circuit?

  • Neither direct nor alternating current
  • Alternating current
  • Both direct and alternating current
  • Direct current (correct)
  • What is the equivalent value of one coulomb of charge in terms of electrons?

  • 6,250,000,000,000,000,000 (correct)
  • 6,250,000
  • 6,250
  • 6,250,000,000
  • What is the equation to calculate the amount of charge passing a point in a circuit?

  • charge = current × time (correct)
  • charge = current + time
  • charge = current - time
  • charge = current / time
