potential difference in parallel circuits

• What does potential difference tell us about in a circuit?

  Energy transfers taking place in a circuit
• What does a potential difference of one volt mean?

  One Joule of energy per Coulomb of charge
• How is potential difference distributed in series circuits?

  It is split between components
• What is a characteristic of parallel circuits?

  They have branches
• How can you measure potential difference in a circuit?

  Using a voltmeter
• What is the potential difference across each branch in a parallel circuit?

  It is the same for all components
• How does the potential difference across components in parallel compare to those in series?

  It is the same across components in parallel
• What does the total potential difference across the bottom branch equal?

  It equals the branch above
