Series and Parallel Circuits

• Give two ways a component can be connected in a circuit?

  Series (same loop)

  Paralell (adjacent loop)
• How does current across two components vary when connected in a series and parallel circuit?

  Series: Total Potential Difference is shared between each component.

  Parallel: Potential Difference across each component is the same.
• If two resistors are connected in parallel, what can be said about their combined total resistance?

  Their total resistance is less then the smallest of the two individual resistances.
• If two resistors are connected in series, what can be said about their total resistance?

  Their total combined resistance is equal to the sum of the two individual resistances.
• Describe the current in a series circuit.

  The current is the same at all positions since the charge only has one path to flow through.
• Describe the current in a parallel circuit.

  The current is shared between the different branches. When the charged reaches a junction it splits.
• How should you connect an ammeter in a circuit to measure current?

  Ammeters should be connected in series with the component they are measuring current through.
• How should you connect a voltmeter in a circuit to measure potential difference?

  Voltmeters should be connected in parallel.
• Why is advantageous to connect lamps in parallel?

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