What happens in a series circuit if one component is removed?
The circuit breaks, and all components stop working.
How is potential difference shared in a series circuit?
The total pd is shared across all components and equals the source pd.
What is the formula for total potential difference in a series circuit?
Vtotal = V1 + V2 + …
What is true about the current in a series circuit?
It is the same through all components.
How do you calculate current in a series circuit?
I = V/R
How is resistance calculated in a series circuit?
Total reistance Rtotal = R1 + R2 + …
What effect does adding a resistor in series have on current?
it decreases the current, as total resistance increases.
What happens to the total resistance when more resistors are added in series?
It increases.
How does adding cells in series affect the potential difference?
Their potential differences add up, increasing the total pd.
Give an example of potential difference in series with cells.
Two 1.5 V cells in series produce a total pd of 3 V.
