DC circuitsQuestion 331 of 1506

In most circuit diagrams, what does the length of the wire between components change?

  1. The voltage polarity across each of the parts
  2. Very little; you can stretch or bend it freely
  3. Whether a part is wired in series or in parallel
  4. The current in every one of the branches
Show answer

Correct answer: Very little; you can stretch or bend it freely

Wire routing matters little for the analysis in most cases.
