Students experiment with the flow of electricity in circuits. The teacher instructs them to wear rubber gloves during the experiment because
1
all of the above
Yes, because circuits must be closed in order for electricity to flow through them.
battery
rubber gloves are insulators
The wire is not insulated and electrical energy flowing from the battery produces heat
plastic straw
Electrical tape
Which of the objects below is NOT needed to test electrical conductivity?
