Answer 1

The component needed to light up the light bulb is a resistor or load.

Step-by-step explanation:

The item needed to light up the light bulb is a resistor or load. In a simple electric circuit, such as the one shown in the figure, a resistor or load is connected to the battery and the light bulb. A resistor helps regulate the flow of current and prevents it from damaging the light bulb.
