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
the electricity flows in the wire, but the actual energy travels throught the EM field.
But that field is there because of the moving electrons in the wire.
Its a little like the saying “Its not the fall that kills you, its the sudden stop when you hit the ground.” Technically correct, and useful in some contexts, but for the average person every day, its the fall that kills you.
