In a parallel circuit, is the voltage across each branch the same?

Explanation:
In a parallel circuit, all branches are connected across the same two nodes, so the potential difference between those nodes is applied to every branch. That means the voltage across each branch is the same as the source voltage. The currents in the branches can differ, depending on each branch's resistance, since I = V/R for each branch. If the resistors happen to be equal, the currents in those branches will be equal too, but the voltage across each branch stays the same regardless of their values.
