The potential difference is the same because the beginning and end points are the same.
pd = p(end) - p(beginning)

Just the fact that you used the word 'around' tells me that you don't understand a parallel circuit.
A parallel circuit is one in which -by definition- the voltage across all elements are equal and the total current through the circuit is the sum of the currents flowing through each individual element of the circuit.
A series circuit is one in which -by definition- the currents through each element are the same and the total voltage across the circuit is the sum of each of the voltages across each individual element of the circuit.

Because the voltage drops across the individual loads of the circuit add up to the total voltage input.
