What is the defining characteristic of a parallel circuit?

  1. All parts are connected between the same two sets of common points.
  2. There is only one path for current, and the current is the same everywhere.
  3. The total resistance is the sum of all the resistor values.
  4. Each part has its own separate battery that feeds it.
Show answer

Correct answer: All parts are connected between the same two sets of common points.

Each path is a branch, and every branch has the same voltage across it.
