I saw a few youtube videos explaining that electricity doesn’t actually travel through wires but directly to the bulb from the battery. I understood their explanation. But now I have a doubt. Since energy flows directly to the bulb, can I shield the bulb in some way such that the circuit is complete and even then the bulb doesn’t light up?
In: Physics
Its true that electricity doesn’t travel through a wire, but it travels on the skin of the wire. This is because like charges repel each other, so the charge flowing down the wire is pushed as far away from each other as they can be which is on the skin of the wire.
Answer to your question, is no.
