In the house of a person who is weak of hearing, a light bulb is also lit when somebody rings the door bell. The ring can be operated both from the garden gate and from the door of the house. Select the correct possible circuit required.
Answers
b is the correct diagram
Answer:
B
Explanation:
Answer is B.
Components connected in parallel are connected so the same voltage is applied to each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
If one of the components in the parallel connection goes wrong, the other components will function without any hindrance.
Therefore, in this case, there are two switches in the circuit, one on the door and one on the gate. Both the switches are connected in parallel and then, the bell and the light bulb are connected in parallel. Each component operate independent of each other and can function if any one goes wrong.
Hence, circuit in option B is correct.
