2.2.2 Characteristics of Parallel Circuits

• What is a parallel circuit?

  Multiple paths for current
• The voltage is the same across all components in a parallel circuit.


  True
• The total resistance in a parallel circuit is less than the resistance of any individual component.
• The voltage across all components in a parallel circuit is equal.


  True
• What is the voltage across each 10Ω resistor in parallel when connected to a 12V supply?

  12V
• In a parallel circuit, the total current divides up among the different paths, with each component receiving a portion of the total current
• In a parallel circuit, the total current divides up among the components.


  True
• What happens to the current in a parallel circuit compared to a series circuit?

  Current is divided
• In a parallel circuit, the voltage is the same across all components.


  True
• What is the total resistance of two 10Ω resistors in parallel?

  5Ω
• In a parallel circuit, the voltage drop across each component is the same, regardless of their resistance
• If a 12V battery is connected to two 10Ω resistors in parallel, what is the current through each resistor?

  0.6A
• The formula to calculate the total current in a parallel circuit is $I_\text{total} =$$I_{1} +$$I_{2} +$$... +$$I_{n}$, where I represents the current
• The formula to calculate the total current in a parallel circuit is $I_\text{total}$
• How is the current through a single component in a parallel circuit calculated?

  I_\text{component} = \frac{V}{R_\text{component}}</latex>
• Match the circuit type with its current distribution:

  Parallel ↔️ Total current divides among components

  Series ↔️ Same current flows through all components
• The formula to calculate the equivalent resistance in a parallel circuit is $\frac{1}{R_\text{total}}$
• In a parallel circuit, the total resistance is always less than any individual resistance.


  True
• One advantage of parallel circuits is that if one component fails, others continue functioning independently due to their separate paths
• Components in a parallel circuit are connected along multiple paths.
• What is the term for calculating the total current in a parallel circuit?

  1.2A
• In a series circuit, the same current flows through all components
• The total resistance in a parallel circuit is less than the resistance of any individual component
• If one component in a parallel circuit fails, the other components can still function.


  True
• How does the voltage distribution differ in parallel and series circuits?

  Same in parallel, different in series
