Questions and Answers

What is the primary function of a volt in an electrical circuit?

  • To determine the electrical resistance between two points
  • To measure the rate of work done in the circuit
  • To regulate the flow of electrons in the circuit
  • To create an electrical current by providing a pushing force (correct)
  • What is the relationship between protons and electrons in a neutral atom?

  • The number of electrons is always greater than the number of protons
  • The number of protons is equal to the number of electrons, but the charges are opposite (correct)
  • The number of protons is inversely proportional to the number of electrons
  • The number of protons is twice the number of electrons
