Series circuit Flashcards
What can be said about the current in a series circuit?
there is the same current through each component
What can be said about the distribution of total pd of the power supply in a series circuit?
the total potential difference of the power supply is shared between the components
What can be said about the sum of the resistance of the components in a series circuit?
the total resistance of two components is the sum of the resistance of each component.
How are voltmeters connected in a series circuit?
In parallel
What happens if you remove or disconnect a component in a series circuit and how does this translate in practise?
If you remove or disconnect one component even, the circuit is broken and they all stop. So in practise, very few things are connected in series.
How do cells being in a series affect the pd provided the cells are connected the same way? (as in p-n)
the pd’s of the cells add up so there’s a bigger pd when more cells are in a series.
How is pd distributed in a series circuit?
the total pd of the power supply is shared between the various components, so the pd’s around a series circuit always add up to the source pd.
Vtotal = V1 + V2 + V3
What is the current like in a series circuit?
It’s the same everywhere.
i1 = i2 = i3
What does a resistor do when added to the circuit?
It lowers the current.
