A
resistors connected in series
current has only one pathway to move through the resistors
resistors connected in parallel
current has multiple pathways to move through the resistors
current
The rate at which charge moves past a fixed point in a circuit.
potential difference
The difference in electrical potential between two points
resistance
Anything that slows down the flow of charge in a circuit.
When resistors are connected in series, current is ….
the same at every point in the circuit
When resistors are connected in series, voltage is …
divided across the resistors.
When resistors are connected in series, the resistance to the flow of current…
increases
