Deck 7: Batteries

Question 1

The voltage of a cell depends on the size and the number of plates.

Answer 1

False

Question 2

A primary cell, when discharged, can be recharged by passing direct current through it in the proper direction.

Answer 2

False

Question 3

When charging a battery, what determines the charging rate? Is it possible to charge a battery with a charging source that has a lower voltage than the battery you want to charge? Why or why not?

Answer 3

The charging rate depends on the voltage difference between the battery voltage and the voltage of the charging source. In all instances, the voltage of the charger must be greater than the total battery voltage. If the charger voltage were lower than the battery voltage, the battery would discharge by driving electrons through the charger.

Question 4

Compare and contrast a traditional battery and a maintenance-free battery.

Question 5

Generally speaking, a larger cell is capable of supplying a higher ____________________ than a smaller cell.

Question 6

The basic unit of the battery is the ____________________.

Question 7

It is a good idea to completely discharge a lead-acid battery before recharging.

Question 8

A fully charged battery will deliver 5 amperes for ____________________ hours if it is rated at 60 ampere-hours.

Question 9

In a traditional battery, glass, rubber, or other insulating materials are used as separators to keep the electrodes from making contact.

Question 10

In a traditional battery, two groups of coated lead plates, known as electrodes, are immersed in a dilute solution of sulfuric acid known as the ____________________.
