series and parallel circuits Flashcards
(8 cards)
1
Q
what’s a series circuit
A
all components are in the same loop
2
Q
what’s a parallel circuit
A
more than one loop/branch
3
Q
what happens to the current/resistance when you add components to a series circuit
A
- current decreases
- resistance of circuit increases
4
Q
what happens to the current/resistance when you add another branch to a parallel circuit
A
- current in other branches stays same
- total current increases
- resistance of circuit decreases
5
Q
what do all the currents in the branches of a parallel circuit add together to make
A
the total current
6
Q
what does the potential difference across each component add up to (series circuit)
A
potential difference across the battery
7
Q
what is the potential difference across each component same as (parallel circuit)
A
potential difference across the battery
8
Q
what is potential difference
A
Potential difference is a measure of how much energy is transferred between two points in a circuit.
