उत्तर

  1. The appliances are connected in parallel.
  2. The potential difference between all appliances is the same with a parallel connection.
  3. No, because each appliance has a different load (resistance), the current passing through them will differ.
  4. Domestic appliances are connected in parallel because the potential difference remains constant.
  5. No, the other devices will continue working since the current passing through them follows separate routes.
