In the following question, two statements are given-one labelled Assertion (A) and the other labelled Reason (R):Assertion (A): When a number of resistances are connected side by side then their combined resistance is less than the smallest inpidual resistance.Reason (R): Connecting a number of resistances side by side provides additional paths for the same current to flow due to which the overall resistance decreases.Select the correct answer to the above question from the following options:- Both A and R are true, and R is the correct explanation of the assertion
- Both A and R are true, but R is not the correct explanation of the assertion
- A is true but R is false.
- A is false but R is true.
(a) Both A and R are true, and R is the correct explanation of the assertion
Explanation
When a number of resistances are connected side by side (parallel) then their combined resistance (or, equivalent resistance) is less than the smallest individual resistance, in fact, less than each individual resistance.
Also, more current flows from the source than would flow for any of them individually, and so the total resistance is lower.
