Question

In a series circuit, what effect will adding more resistors to the circuit have?

It will decrease the equivalent resistance which will decrease the total current.
It will increase the equivalent resistance which will decrease the total current.
It will increase the equivalent resistance which will increase the total current.
It will decrease the equivalent resistance which will increase the total current.
The number of resistors will not affect the circuit in anyway.

Answer 1

The answer is the second sentence.

Answer 2

Answer: The correct option is "It will increase the equivalent resistance which will decrease the total current".

Step-by-step explanation:

In the series combination, the equivalent resistance of the circuit is more than the equivalent resistance of the circuit in the parallel combination.

The resistance is inversely proportional to the current.

The value of the current across each resistors in the series circuit is same.

If the more resistors are added to the series circuit then the overall resistance of the circuit will increase. It may lead to decrease in the value of the total current.

Therefore, the correct option is "It will increase the equivalent resistance which will decrease the total current".
