At its most basic level, a battery is a can full of chemicals that produces ____.
protons
neutrons
electrons
From the batteries in our cars to the batteries in our flashlights and laptop computers, they're all essentially cans of chemicals that produce electricity in a process called electrochemical reactions.

The areas of a battery that are marked positive (+) and negative (-) are called:
reactors
terminals
A battery is marked positive and negative at its two terminals. In a small battery (like an AA, C or D), these are just the opposite ends, while in a larger battery (like a car battery), the terminals are two heavy lead posts.

In which direction must electrons within a battery flow for a chemical reaction to take place?
positive to negative
negative to positive
For a chemical reaction to occur within the battery, electrons must flow from the negative to the positive terminal. The reaction doesn't start until you plug the battery in to make a circuit.

In 1800, Alessandro Volta made the first battery by layering plates of silver and zinc with blotting paper that had been soaked in salt water. What was this primitive battery called?
voltaic pile
The very first battery was called a voltaic pile. Each layer in the pile increased the battery's voltage.
voltube
Volta stack

Which of the following names is not used interchangeably with Daniel cell, the 17th-century battery commonly used in telegraphs and doorbells?
gravity cell
wet cell
charged cell
The Daniel cell is also known as the gravity cell, wet cell and crowfoot cell. It's made from copper and zinc plates and copper and zinc sulfates.

When was the prototype for the rechargeable battery invented?
1795
1901
1859
In 1859, a French physicist named Gaston Plante created the lead acid cell. It later became the world's first rechargeable battery.

Nickel-cadium batteries can malfunction when they're overcharged -- that is, recharged before they've had a chance to discharge more than 50 percent of their power. What's this common problem called?
charge maximization
memory effect
When a nickel-cadium battery is recharged before it discharges the majority of its power, it essentially "forgets" that it could fully discharge to begin with. This problem is termed the memory effect. You can avoid the memory effect by allowing the battery to fully discharge once every two to three weeks and then recharging it.

parallel
serial
