Question

Assertion: Resistors connected in series are more effective than those connected in parallel.

Reason: Resistance of resistors increase when connected in series.
​

Answer 1

Answer:

assertion and reason is both correct

Answer 2

Answer:

The assertion is true and the reason is false here.

Explanation:

Here in the assertion, we have been given that the resistors that are generally connected in series are more effective than those resistors which are connected in parallel connection.

This is true as we know that in the series connection of the particular resistors the effective resistance is simply the sum of the resistors. Therefore the net effective resistance increases as a result. And hence the circuit becomes more effective for blocking the current flow through them.

The reason here has been mentioned that the resistance of resistors increases when they are connected in series. This is false as we know that the effective resistance of the circuit increases whenever the particular resistors are connected in series and not their individual resistance. Their own particular resistance remains identical regardless of whether they are in the series connection or parallel.

Therefore the assertion here is true and the reason is false.
