what is effect on the closed circuit current
To what end? I don't understand.can we connect ac source series with dc source?

Me either. :huh:
In theory, yes, sure. The resulting voltage would be the AC voltage riding on the DC voltage.
And the resulting current would still be the total voltage divided by the total resistance of the load.
But in reality, I wouldn't try this at home. Most batteries and DC supplies have a very low current rating, or they may not like the AC forcing current or votlage the opposite direction.
They could easily explode if connected to something like a load through 120V AC source.

Correct me if I got it wrong here. I think you wanted to mix AC into a DC current flow.
That said, why do you have to physically "connect" when you can just superimpose an AC signal on the DC line by induction. This is basically the theory behind non-contact, switched spark initiation in Tungsten Inert Gas (TIG) welding machines. An HF generator output is routed into a coil turned around the output lead of the DC welding source and the arc is initiated when the torch head (negative terminal) comes near enough with the workpiece to be wielded (positive end).
just i saw one question ac source with dc of RLC circuit .in your first reply itself i got a answer that capacitor will block dc ..I just re-read the OP and I have no idea if my last few post are even what he is trying?:?
Saw the "close circuit" and my mind just went to CCTV?

A battery Charger, done all the time.:slaphead:
