What is the expression of the capacity of a battery? Correct Answer Ampere-hour rating

The capacity of a battery is measured in ampere-hours.

The ampere-hour capacity is equal to the product of the current in amperes and the time in hours during which the battery is supplying current.

The ampere-hour capacity varies inversely with the discharge current. The size of a cell is determined generally by its ampere-hour capacity.

The capacity of a cell depends upon the following factors:

  • The area of the plates in contact with the electrolyte
  • The quantity and the specific gravity of the electrolyte
  • The type of separators
  • The general condition of the battery (degree of sulfating, plates buckled, separators warped, sediment in the bottom of cells, etc)
  • The final limiting voltage

Which of the following statements about Regular Expression is/are incorrect? A. The union of two regular expressions is also a regular expression B. The concatenation of two regular expressions is also a regular expression C. The iteration of a regular expression is also a regular expression
Two pipes are connected to tank 1 and one pipe connects tank 1 and tank 2 at the bottom of both tanks. At first pipe A and pipe B will filling tank 1 and then pipe C would be opened to fill tank 2. Capacity of tank 1 is twice capacity of tank 2. Pipe C takes 8 minutes to fill the whole tank 2 wherein discharging capacity of pipe C is 62.5 liters per minute. Ratio of time taken by pipe A and B to fill the tank when operating alone is 4 : 5 then find approximate discharging capacity of pipe A and B in liters/ minute if both the pipes discharge equal amount of water in tank. Time taken by pipe A and B to fill the tank 1 is 20/ 3 minutes
A pipe, working at full speed, can fill an empty cistern in 1 hour. However, during the first hour it worked at one-twenty-fourth of its capacity, during the second hour at one-twelfth of its capacity, during the third hour at one-eighth of its usual capacity, during the fourth hours at one-fourth of its usual capacity and during the fifth hour it was only one-half as efficient as it was supposed to be. A second pipe also displayed similar performance, but if it worked at full speed would have filled the empty cistern in 2 hours. Together with a drain pipe that drained water out of the tank a constant rate, the empty cistern could be filled in 5 hours, all the three pipe working concurrently. How many hours will it take the drain pipe to empty the filled cistern if no other pipe was functioning during the time?
A motor is used to fill and empty the cooler tank. The tank has a capacity of 3360 m3. The emptying capacity of the pump is 20 m3/minute more than its filling capacity and the pump needs 14 minutes lesser to empty the tank than it needs to fill it. What is the filler capacity of the pump?
