A battery provides 12 V to a circuit. If the circuit contains 4 identical loads, determine the potential difference across each load if they are connected in (a) series and (b) parallel.
Please help me answer this question :)

(a) series :
total R = (r1+r2+r3+r4)
total I = 12/R
potential at r1 = I x r1
potential at r2 = I x r2
potential at r3 = I x r3
potential at r4 = I x r4
(b) parallel
potential are same as total V = 12 v
total R = (r1+r2+r3+r4)
total I = 12/R
potential at r1 = I x r1
potential at r2 = I x r2
potential at r3 = I x r3
potential at r4 = I x r4
(b) parallel
potential are same as total V = 12 v

Potential difference and voltage mean the same thing.
Potential difference across wires is zero, for all intents and purposes. Therefore, you'll see that the voltage at either end of the load in parallel are the same.
If there's connected in series, identical loads will divide the total load equally.
I suggest to make a drawing, like the one in the links below.
