Question
The accompanying figure shows some electrical appliances connected in a circuit in a house. Answer the following questions.
- By which method are the appliances connected?
- What must be the potential difference across individual appliances?
- Will the current passing through each appliance be the same? Justify your answer.
- Why are the domestic appliances connected in this way?
- If the T.V. stops working, will the other appliances also stop working? Explain your answer.

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