CELL CAPACITY
The amount of electrical energy that a cell can provide from new to the end of its useful voltage on load is called the cell capacity and is quoted in Ampere hours (A-h).
Capacity varies with the amount of current drawn from the cell, the greater the current the lower the capacity, therefore capacity is normally quoted at a standard rate. The 1hr rate is the internationally accepted standard for Nickel Cadmium cells, with 10 hr or 20 hr rates being used for Lead Acid cells.
A cell quoted at 40A h at the 10 hr rate will provide 4 Amps continuously for 10 hours.
A battery quoted at 40A h at the 1 hr rate will provide 40 Amps continuously for 1 hour.
A 40 A-h cell will only be able to provide a discharge current of 80 amps for approximately 20 minutes, not 30 minutes as may be expected by calculation. Similarly, it will be able to supply a discharge current of 20 amps for longer than the expected 2 hrs.
The capacity of a cell is also affected by its age, the older a cell, the lower its capacity, therefore the only way of determining actual capacity is to measure it.
What is the meaning of Polarization? Polarization is a quality that is only exhibited by transverse waves. For light waves, the polarization identifies the direction of vibrati
Explain the Resonance of Sound in Air Columns Wind instruments use vibrations in air columns to generate notes. The end that air is blown into is all time considered an open en
Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
what is the ratio of the frictional force and the normal force ?
