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

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

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?
Current division
What is the key characteristic of current in a parallel circuit?
It divides among paths
In a parallel circuit, the voltage across components is the
same
across all paths.

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
In a series circuit, the current is divided among the components.
False
