e. open the circuit



Answer :

GinnyAnswer

Final answer:

Increasing the resistance of the circuit and opening the circuit would reduce the brightness of the light bulb.


Explanation:

Increasing the resistance of the circuit (c) and opening the circuit (e) would cause the light bulb to shine less brightly. When resistance increases, it limits the current flow, reducing the brightness of the bulb. Opening the circuit disrupts the flow of electricity, dimming the light bulb.
