components(i.e., block the dc components). it allows the ac
components to pass through.

why the capacitors works on ac only..

Answer / nishant naveen

Reactance of capacitor X = 1/(2πfc)

Since f=0, for dc frequency is zero.
So, Reactance X will be infinity for dc.

means capacitor blocks dc and allows only ac to pass

Answer / rakesh

Only high frequency
allowed to pass
through the capacitor,
& dc supply has
0(zero) frequency due
to this reason
capacitor work on only
ac.

In power generator sets, when they are coverted from 50hz to 60hz, the kva rating after conversion increases. For example, the manufacturer of a perkins 200kva @ 50Hz generator set has mentioned it to become 220kva after converstion to 60hz. What is the relation between the frequency & the KVA rating. Any formula please.
