# how current flows in a parallel circuit as the potential difference is same?

Since we know current can not flow in a wire if there is no potential difference in its two terminals. How current flows in a parallel combination where each load has equal potential difference in its two terminals?

In a parallel combination each circuit has the same voltage $U$, which can be easily shown with Kirchhoff's laws. But the potential difference between the two knots of the parallel wired part is nonzero. Therefore current flows, depending on the resistance (where the voltage drops) of the parallel-connected circuit (so that the voltage $U$ is the same in each circuit).
