Big picture and laws

Comparison of a series circuit with two resistors in one loop and a parallel circuit with two branches, showing current and voltage labels A series circuit has one path for current, while a parallel circuit has more than one path between the same two nodes. That single visual difference explains why current, voltage, and resistance behave differently.
