Model Answer

Two practical advantages of parallel connection in domestic circuits:

  1. Each appliance operates at the same voltage (the supply voltage), so every device works at its rated voltage and functions properly.
  2. Each appliance can be switched ON or OFF independently — if one appliance fails or is turned off, the others continue to work without any interruption.

Explanation

Examiners expect exactly these two points: (i) equal (full) voltage across each appliance, and (ii) independent operation. Exercise 18(c) asks why series is NOT used for domestic circuits — the flip side of that gives the parallel advantages. Avoid vague answers; name the specific benefit clearly. One point = 1 mark each.
