The correct answer is C. lead-acid battery.
Lead-acid batteries are the most common type of battery used in electric power stations. They are also used in cars, boats, and other vehicles. Lead-acid batteries are made up of two lead plates that are submerged in a sulfuric acid solution. When the battery is charged, the lead plates are converted to lead sulfate. When the battery is discharged, the lead sulfate is converted back to lead and sulfuric acid.
Lead-acid batteries are a reliable and affordable source of power. They are also relatively easy to maintain. However, lead-acid batteries have a limited lifespan and must be replaced periodically.
Nickel-cadmium batteries are another type of battery that is used in electric power stations. They are more expensive than lead-acid batteries, but they have a longer lifespan. Nickel-cadmium batteries are also more resistant to vibration and temperature extremes.
Zinc-carbon batteries are the least expensive type of battery. They are not used in electric power stations, but they are used in many other applications, such as flashlights and toys. Zinc-carbon batteries have a short lifespan and must be replaced frequently.
In conclusion, the storage battery generally used in electric power station is C. lead-acid battery.
