Recall / Warm-Up

Which of the following is the defining property of a parallel circuit?

Components are connected between the same two nodes, so all branches have the same voltage.

All components carry the same current.

The equivalent resistance is the sum of the individual resistances.

Adding more branches increases the total resistance.
