parallel circuits Flashcards
how are components connected in parallel circuits
they are separately connected to the +ve and -ve of the supply (except ammeters which are always connected in series)
what happens if you remove or disconnect one of them
it hardly affects the others at all
what do everyday circuits often include
a mixture of series and parallel parts
what are examples of everyday circuits
care
household appliances
how is the potential difference in parallel circuits
the pd is the same across all components
What is the source of potential difference that each component gets
All components get the same potential difference which means bulbs connected at parallel will be at the same brightness
how is current shared
between branches
what is the total current flowing around the circuit equal to
the total of all currents through separate components
what are junction
where the components either split or rejoin
what happens to the current when two identical components are connected in parallel
the same current will flow through each component
what happens if you add a resistor in parallel
it reduces the total resistance
what happens if you have two resistors in parallel
the total resistance is resistance of tue smallest of the two resistors
