Question

The voltage in the circuit is increased, but you want the light bulb's brightness to remain the same. Which statement best describes what you can do to the circuit to make this possible?

Decrease the number of switches
Decrease the length of the wire
Increase the connection of batteries
Increase the number of resistors

Answer 1

Answer: Increase the number of resistors

Explanation: When the voltage is increased, the only way for the light bulb's brightness to remain the same is to increase resistance so that the resistance and voltage are increasing at a proportional rate. Also I got 100 on the exam.

Answer 2

Increasing the number of resistors

Step-by-step explanation:

Increasing the number of resistors would be the best option to make the light bulb's brightness remain the same when the voltage in the circuit is increased. This is because resistors are used to control the flow of current in a circuit, and increasing the number of resistors would reduce the amount of current flowing through the circuit, thus maintaining the same brightness of the light bulb. The other options, such as decreasing the number of switches, decreasing the length of wire, or increasing the connection of batteries, would not have a significant impact on the flow of current through the circuit and therefore would not be effective in maintaining the same brightness of the light bulb.
