Answer
Answer:
The first and third arrangements will result in a lit bulb.
Explanation:
Step1: Understand circuit - completion principle
A bulb lights up when there is a complete circuit allowing electric current to flow from the positive terminal of the cell, through the bulb, and back to the negative terminal of the cell.
Step2: Analyze the first arrangement
The wire connects the positive terminal of the cell to one terminal of the bulb and another wire connects the other terminal of the bulb to the negative terminal of the cell, forming a complete circuit. So, the bulb will light up.
Step3: Analyze the second arrangement
The wire only connects one terminal of the bulb to the positive terminal of the cell. There is no connection from the other terminal of the bulb to the negative terminal of the cell, so no complete circuit is formed and the bulb will not light up.
Step4: Analyze the third arrangement
The base of the bulb is in contact with the negative terminal of the cell and the wire connects the positive terminal of the cell to the side - terminal of the bulb, forming a complete circuit. So, the bulb will light up.
