Faraday?s law of electrolysis
The charge required to liberate one-gram equivalent of any substance is known as Faraday’s constant.
Ampere - hour
The capacity of a cell is measured in Ampere - hour.
All of the above
Active materials of a lead acid cell are Spongy lead, Lead peroxide and Dilute sulfuric acid.
Sulphation in a lead-acid battery occurs due to Incomplete charging.
Rate of charge
The capacity of lead-acid cell does not depend on its Rate of charge.
During charging the specific gravity of the electrolyte of a lead-acid battery Increases.
Lead peroxide and lead
When a lead-acid battery is in fully charged condition, the colour of its positive plate is Dark brown.
The active materials of nickel-iron battery are Nickel hydroxide, Powered iron and its oxide and 21 % solution of KOH.
The value of specific Gravity of acid when a lead-acid battery is fully charged is 1.285.
Always greater than one
The ratio of ampere-hour efficiency to watt-hour efficiency of a lead-acid cell is Always greater than one.
Specific gravity of electrolytes
The best indication about the state of charge on a lead-acid battery is given by Specific gravity of electrolytes.
The storage battery generally used in electric power station is Lead-acid battery.
Higher than the battery voltage
The output voltage of a charger is higher than the battery voltage.
Increase the voltage rating
Cells are connected in series in order to Increase the voltage rating.
Water is neither formed nor absorbed
During the charging and discharging of a nickel-iron cell Water is neither formed nor absorbed.
