Series and Parallel Circuits

HideShow resource information
In a sereis circuit, components connected in a line, end to end...
apart from voltmeters that are connected in parallel
1 of 16
P.D. is shared - the voltages around a circuit always...
add up to equal the source voltage
2 of 16
The same current flows everywhere - the size of the current is determined by...
the total p.d. of the cells and the total resistance of the circuit
3 of 16
The total resistance is the sum of all the resistances. The bigger the resistance of a component...
the bigger the overall resistance
4 of 16
Cell voltages add up - There is a bigger p.d. when...
more cells are in series, provided they are connected in the same way
5 of 16
Also, if you remove or disconnect one component....
the circuit is broken and they all stop
6 of 16
In a parallel circuit, each component is separately connected in the circuit and...
if you remove or disconnect one, it will hardly affect the others at all
7 of 16
P.D. Is the same across all components - All components get the full source P.D. so the voltage is...
the same across all components
8 of 16
This means that identical bulbs connected in parallel will be...
at the same brightness
9 of 16
Current is shared between branches - The total current flowing around the circuit is equal to...
the total of all the currents through the separate components
10 of 16
There are junctions where the current...
either splits or re-joins
11 of 16
The total current going into a junction...
as to equal the total current leaving
12 of 16
If two identical components are connected in parallel then...
the same current will flow through each component
13 of 16
Ammeters always connect....
in series
14 of 16
Voltmeters always connect...
in parallel with a component
15 of 16
In a car, everything can be turned off separately and...
everything gets the full voltage of the battery,
