series and parallel circuits

• In a series circuit, how many loops are present?

  One
• How are components connected in a series circuit?

  One after the other
• How many loops do parallel circuits contain?

  More than one
• What happens if one component is disconnected or broken in a series circuit?

  The whole circuit stops working
• In a series circuit, how is the potential difference of the cell or battery distributed?

  Shared across all components
• Why are series circuits not commonly used in practice?

  Due to the single point of failure
• What is consistent throughout a series circuit?

  Current
• What instrument measures current in a circuit?

  Ammeter
• How is an ammeter connected in a circuit to measure current?

  In series
• Where can an ammeter be placed in a series circuit to measure the current?

  Anywhere in the loop
• Which law relates current, voltage, and resistance?

  Ohm's law
• In a series circuit, how is the total resistance calculated?

  Sum of individual resistances
• What does the green symbol '∑' represent?

  Sum or total
• Why are ammeters usually ignored in resistance calculations?

  They have tiny resistances
• What instrument measures voltage across a component?

  Voltmeter
• How is a voltmeter connected to measure the voltage across a component?

  In parallel
• How should an overall circuit with a voltmeter in parallel be treated?

  As being series
• According to Ohm's law, which components have a higher share of the voltage?

  Components with greater resistance
• Why do components with greater resistance have a higher share of the voltage?

  More force needed to push charge
• What is the relationship between voltage, current and resistance described by?

  Ohm's law
• How does current behave in a series circuit?

  It is the same everywhere
• How does voltage behave in a series circuit?

  It is shared across components
• How does resistance behave in a series circuit?

  It is the sum of resistances
• How do the differences between series and parallel circuits impact measurements?

  Affects current, voltage, resistance calculations
• What is a key characteristic of parallel circuits in terms of loops?

  They have more than one loop
• What does each loop typically contain in a simple parallel circuit?

  A single component
• Why are parallel circuits generally more useful than series circuits?

  Each component has its own loop
• What happens to other components in a parallel circuit if one component breaks?

  The other components still work
• What type of configuration do many practical circuits have?

  A mix of series and parallel parts
• In truly parallel circuits, what potential difference do all components receive?

  Their full source potential difference
• How is current distributed in a parallel circuit?

  It is shared between all loops
• What is the relationship between the currents in each loop and the total current?

  They add up to the total current
• In a two-loop parallel circuit with a total current of 4 amps, what could be the current distribution?

  Three amps and one amp
• What determines how the current splits between loops in a parallel circuit?

  The resistance of the components
• Which loops take a lower share of the current?

  Loops with greater resistance
• How can the flow of current through multiple paths be visualized?

  As water flowing down a hill
• What path will most of the current take?

  The path of least resistance
• What is the relationship between adding components in parallel and the total resistance?

  The total resistance decreases
• What happens to the overall resistance as more loops are added in parallel?

  The overall resistance will be lower
• Why does adding more routes in parallel reduce the overall resistance, even with high resistance routes?

  It increases the options for flow
