What happens to the current at a junction in a parallel circuit?

In a parallel circuit the current divides when it comes to a junction. Part of the current flows through one branch and the other part flows through the other.

When the two branches have the same resistance, the same current flows through each branch.

When the two branches have different resistances, a bigger current flows through the branch with the smaller resistance - it's just easier this way!

Hope i helped ;)
