P2 series and parallel circuits Flashcards
In a series circuit, is current the same everywhere?
Yes.
What happens to voltage in a series circuit?
It is shared between components.
How do you calculate total resistance in a series circuit?
Add up all individual resistances.
What happens to resistance if you add more resistors in series?
It increases.
In a parallel circuit, what happens to voltage across each branch?
It stays the same.
What happens to current in a parallel circuit?
It splits between branches.
If you add more resistors in parallel, what happens to total resistance?
It decreases.
Why are household circuits wired in parallel?
So that each device gets the full voltage.
What happens if one component breaks in a series circuit?
The whole circuit stops working.
What happens if one component breaks in a parallel circuit?
The rest of the circuit still works.
Why do parallel circuits use more current than series circuits?
Because each branch has its own path for current.
What does a voltmeter measure?
Potential difference (voltage).
Where should a voltmeter be placed in a circuit?
In parallel with a component.
What does an ammeter measure?
Electric current.
Where should an ammeter be placed in a circuit?
In series with a component.
