AInterconnections get complicated
BInstruments get calibrated
CInsulators get complicated
DIncrements get calculated
Answer & Solution
Correct answer: A. Interconnections get complicated
1. Some networks cannot be reduced by combining pairs.
2. Kirchhoff's rules exist precisely for those.
3. The series and parallel formulae are not always sufficient to determine all currents and potential differences.
4. So the answer is interconnections get complicated.
