A3-ohm resistor and a 6-ohm resistor are
connected in parallel across a 9-volt battery.
which statement best compares the potential
difference across each resistor?
(1) the potential difference across the 6-ohm
resistor is the same as the potential
difference across the 3-ohm resistor.
(2) the potential difference across the 6-ohm
resistor is twice as great as the potential
difference across the 3-ohm resistor.
(3) the potential difference across the 6-ohm
resistor is half as great as the potential
difference across the 3-ohm resistor.
(4) the potential difference across the 6-ohm
resistor is four times as great as the potential
difference across the 3-ohm resistor.
