In this article, we will be discussing a tricky question on Electricity: Will the bulb still light up when the batteries are arranged in the wrong order?
Recently, I was sent a question on Electricity from a parent who was revising together with her child.

This question is pretty tricky and I thought it would be good to share it with you.
Question: The batteries are arranged in the wrong order. Will the bulb still light up?
Answer: The bulb will still light up because the two bulbs with the positive ends facing each other would “cancel” each other out. Thus, there will still be one battery (in red) in this circuit that will cause the bulb to light up.
Hope this explains!
