A 100% string efficiency indicates:

  1. Potential difference of n-1 discs = P.D of nth disc
  2. Potential difference of nth + n-1 disc = P.D of all other discs
  3. Potential across each disc is the different
  4. Potential across each disc is the same

Correct answer: 4. Potential across each disc is the same
