• What are the two ways that a component can be connected in a circuit?

  Series and parallel
• What are the characteristics of components connected in series and parallel?

  • Series: Total potential difference (P.D) is shared between components.
  • Parallel: P.D across each component is the same.
• What can be said about the total resistance of two resistors connected in parallel?

  The total resistance is less than the smallest of the two individual resistances.
• What can be said about the total resistance of two resistors connected in series?

  The total combined resistance is equal to the sum of the two individual resistances.
• How is the current described in a series circuit?

  The current is the same at all positions in a series circuit.
• How is the current described in a parallel circuit?

  The current is shared between the different branches in a parallel circuit.
• How should an ammeter be connected in a circuit to measure current?

  An ammeter should be connected in series with the component being measured.
• How should a voltmeter be connected in a circuit to measure potential difference?

  A voltmeter should be connected in parallel to the component being measured.
• Why is it advantageous to connect lamps in parallel?

  If one lamp blows, the rest will be unaffected and can still receive current.
