Parallel circuit

• How do parallel circuits treat potential difference, current, and resistance?


  They provide full source potential difference to each component, share current among loops, and have lower total resistance with more components.
• What is a characteristic of parallel circuits regarding components?


  Each component has its own loop, so if one component breaks, the overall circuit remains intact.
• What happens in a house if one light bulb blows in a parallel circuit?


  All other lights will still work.
• What is the relationship between series and parallel circuits?


  Circuits can be a mix of series and parallel parts.
• What happens to the potential difference across components in a parallel circuit?

  The potential difference is the same across the components in a parallel circuit
• If a circuit has a 12 volt battery, what is the potential difference across each component?

  Each component will have 12 volts across them.
• How is current shared in a parallel circuit?

  The current is shared among all loops, depending on the resistance of the components.
• If a circuit with two loops has a total of 4 amps flowing through it, what could be the current distribution?

  It could be 3 amps in the first loop and 1 amp in the second, or 2 amps in each loop.
• How does resistance affect current distribution in parallel circuits?


  Loops with greater resistance take a lower share of the current.
• What happens to the total resistance of a parallel circuit as more components are added?


  The total resistance decreases as more components are added.
• Why does adding more components in parallel lower the total resistance?

  It increases the options for current flow, making it easier for current to pass through.
• What are the key characteristics of parallel circuits?


  • More than one loop
  • Each loop contains a single component
  • Potential difference is the same across each component
  • Current is shared among loops
  • Total resistance decreases with more components
• How does the current distribution in a parallel circuit depend on resistance?


  • Higher resistance loops receive less current
  • Lower resistance loops receive more current
  • Total current is the sum of currents in each loop
• What is the effect of adding components in parallel on total resistance?


  • Total resistance decreases
  • More paths for current flow
  • Easier for current to pass through
