A: Unit of potential difference, measures the amount of work/unit of charge
Q: Describe what an anode is. Cathode?
A: Anode: Gives electrons to the cathode. Cathode: Receives electrons from the anode.
Q: What is the purpose of the electrolyte?
A: To separate the anode and cathode and allow for the electrons to flow through the battery
Q: How to batteries die? What makes a rechargeable battery different?
A: When there are no more electrons the anode can give. Rechargeable batteries are able to reverse this process.
Q: Which metals create the highest voltage?
A: A more reactive metal(anode) and a lesser reactive metal(cathode)
Q: How does a current differ from a volt?
A current is how fast the electrons move through the wire whereas the volt is how fast the electrons are initially pushed.
Q: Why must you need a wire for a battery to work?
A: You need something to connect the anode and cathode so the electrons can run freely.
