Because batteries store large amounts of energy, there are certain hazards that are associated with battery operation. These hazards must

The lead-acid battery is the most common type of battery in use today. There are other types of storage batteries,

Once the basic theory behind the operation of batteries is understood, we can apply these concepts to better understand the

In a lead-acid battery, two types of lead are acted upon electro-chemically by an electrolytic solution of diluted sulfuric acid

A battery converts chemical energy to electrical energy. This conversion enables electrical power to be stored. The purpose of a

Specific gravity is defined as the ratio comparing the weight of any liquid to the weight of an equal volume

Batteries are used for a wide variety of services throughout technology today. To begin to study battery operation and characteristics,

When a capacitor is connected to a DC voltage source, it charges very rapidly. If no resistance was present in

Capacitors in series are combined like resistors in parallel. Figure 13 : Capacitors Connected in Series The total capacitance, CT,
