What happens to the current in a series circuit if more resistors are added?

  1. The current fluctuates

  2. The current decreases

  3. The current increases

  4. The current stays the same

The correct answer is: The current decreases

Adding more resistors in series will result in an increase in total resistance in the circuit, causing the current to decrease. This is because the current follows the path of least resistance and as more resistors are added, the total resistance in the circuit increases, making it harder for the current to flow through. Therefore, option B is the correct answer.
