DC circuitsQuestion 700 of 1506

Which rule applies to a series circuit?

  1. All components have the same voltage
  2. Resistances combine to a smaller total
  3. All components carry the same current
  4. Branch currents add to the total
Show answer

Correct answer: All components carry the same current

Series parts form one path, so the same current flows through all of them.
