Can you explain what your asking? I know English is a second language for you, but it's hard to understand what your trying to ask.

suppose if you are trying to take a photo of transmssion lines, is it the situation that the current in the lines fllows to ground through you due to camera flash light?

I myself, haven't heard of this happening before but that's not saying that if you got to close HV transmission lines that you can't get zap, I don't think a camera flash would induce an arc, just your body would act as a lighting rod. I've also been in micro-wave repeater stations where there's a lot of EMF and seen fluorescent tubes glowing and not connected to any fixture or power source.

No.

It can flow through a conductor, like a human, so don't get too close.

Current flow can not be aggravated (either increased or decreased) by light, in your scenario. It CAN be aggravated by light in some scenarios where the light source is intense enough to cause heating of the conduction system. This is not the case with a camera flash.

I calculated many years ago that for a "standard" 1KJ studio flash unit 660V at 400A flowed during the short burst of flash.

A few photographers have died because they didn't understand the power involved. I used to dread working with 4KJ units, they had a bad habit of exploding. The biggest problem comes when a unit is charged and an extra head is plugged in, I've had a plug unit explode in my hand doing this when the brain was in neutral.

madhu sudhan, I surprised by this question coming from you, looking at the answer you gave on this thread, it would seem that you would have an idea of what would or would not happen taking a picture of transmission lines with a camera, with or without the flash being on

Well suppose you are taking a picture of HV transmission lines in your mobile phone camera or handy digi-cam if current flows into the flash light you could be a dead meat. Think about it...dont get closer to HV lines and attemp to touch when getting pictures or else you could be a real toasted meat.
