Question

The accompanying figure shows some electrical appliances connected in a circuit in a house. Answer the following questions.

1. By which method are the appliances connected?
2. What must be the potential difference across individual appliances?
3. Will the current passing through each appliance be the same? Justify your answer.
4. Why are the domestic appliances connected in this way?
5. If the T.V. stops working, will the other appliances also stop working? Explain your answer.

Answer 1

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.
