Concept:Domestic lighting uses parallel connections so each lamp operates independently at the same mains voltage.
Explanation:In a parallel arrangement, every lamp is connected directly across the supply.
Each lamp therefore receives the full mains voltage and glows normally.
Parallel wiring has a smaller total resistance than series wiring.
For a fixed voltage, lower resistance leads to lower heat losses because heat produced is proportional to resistance:
heat∝R.
Also, if one lamp burns out, the other lamps remain lit, which is desirable in homes.
Thus lamps in domestic lighting are not connected in series, convergent, or divergent paths.
Answer:D. parallel
