Answer / prashant

whenever we switch on any appliance at that instants current
is the quantity that is been actually used. Batteries are
used to supply power hence forth their ratings are mentioned
in AH ( Ampere Hour ) i.e current capacity that can be
delivered in a period of 1 hour.you can divide Amp-hr by 60
to get amperes used in a minute.both are readings for
current only

Answer / fakhir

A battery can deliver the power for limited time period.
Battery rating in AH reflects its capability to supply X
amps in a period of one hour. Operational time of a battery
thus can be extended in proportion to amps loading i-e
lower the connected load higher the service time. Thus
expressing capacity in absolute 'amps' does not make
sense.

Answer / sunil kaushik

amp-hour is means that a battery can supply toatl ahr for 20 hrs .so by dividing the amps with hous we can get the a/hr.



i do not why this is use

Answer / venkatesan.j

It reflets how much current it can supply for own hour, but
if reduced current is drawn then the time period it can
supply is obtained dividing the AH by current drawn.

why transformer rating is always in KVA

we done magnetic balance test for 33KV /440V transformer in our company , but the ratio out is confusing us Voltage applied in RY = 440 , at RB = 320 and YB = 60 RY 440 = ( RB + YB ) 380 only Please let me know what type of problem is it.
