1. Why did Ben Franklin name one type of electricity positive (+)?

He was positive that it was electricity

He felt it had an excess of electric "fluid" over the other type

To corresponds to the positive terminal on a battery

2. Why did Volta name the ends of a battery positive and negative?

Just to be opposite of Franklin's views

That is how they are marked on every battery you buy

According to the metals used in the voltaic pile of the batter

3. What direction do electrons move in a DC circuit?

The opposite direction of the current

Electrons do not move in a circuit

Electrons flow along with the current

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
