David and Naomi organized a group of objects into the data table shown in the picture. The objects have been classified either as an electrical conductor or insulator. Which item is classified incorrectly.
glass bead
Plastic plate
aluminum foil
silver bracelet
wooden stick
Why has the plastic coating been stripped off to expose the copper wire?
So you can verify that there really is copper wire inside
So the electric current can pass between the copper and the rest of the circuit
So the wire can be bent
