Inscriptions on a battery

The amount of current, which is taken in by a battery in a given time or given out during discharging is called the capacity. In the United States the term 'reserve capacity' is used. Here, during the discharge, a current of 25 A is stipulated to determine the capacity.

K = I · t

I =

Places behind the comma: 2 3 4 5


Var. set:

I = 3,4 A; t = 5 h 15 min = 5,25 h

Var. asked for:

K in Ah


K = I · t = 3,4 A · 5,25 h = 17,85 Ah               Top of page               Index
