In the following question, two statements are given - one labelled Assertion (A) and the other labelled Reason (R):
Assertion (A): If hundreds or thousands of electric bulbs are to be joined for decorating a building, then they should be connected in series with the mainline.
Reason (R): When a large number of electric bulbs are connected in series, they can be controlled with just one switch.
Select the correct answer to the above question from the following options:
(a) Both A and R are true, and R is the correct explanation of the assertion.
(b) Both A and R are true, but is not the correct explanation of the assertion.
(c) A is true but R is false.
(d) A is false but R is true.
(a) Both A and R are true, and R is the correct explanation of the assertion.
Explanation
If we want to connect a large number of electric bulbs for decorating buildings and trees as during festival like Diwali and on any special occasion such as marriage or birthday function, then the series circuit is better because all bulbs connected in series can be controlled with just one switch.
In a series circuit, the current that flows through each of the components is the same, therefore it is also safer because the current in it is smaller.
