Question Will this work if im using a anti static wrist strap when repairing a laptop

So i was thinking that i would connect it to the ground terminal of the outlet( I live in India so its the top one) but I'm scared of getting shocked bcz of a faulty ground point etc. So i was thinking if i take a 3 prong DC adapter(Its like 5V) that i have lying around, cut out the wire and insulate the other 2 wires and connect the strap and mat to it.
Will that work?
 
how will adding extension cable to faulty ground point make it any less faulty?
Depending on what/how the dc adapter does it's job, ground is either straight to outlet ground (potentially faulty still) or not ground at all.

I would verify that the ground terminal in outlet is working as expected and then use it.

I said that I'm scared of getting shocked due to a faulty ground connection(maybe live wire is attatched to ground wire or something). I just thought it would be safer to use a Adapter(5v 2a) than using AC outlet(220V)

Many anti-static wrist straps in the labs where I worked were connected to the mains safety earth via a 1MegOhm resistor. This resistor was usually built into a dummy 3-pin plug top plugged into a spare mains socket on the work bench.

If you have any doubts about the safety of your mains earth, consult a qualified electrician immediately.

If you haven't got a socket you trust not to have wired live->ground, what are you going to plug your PC into? Because there the whole case could be 230V.

Assuming you have something plugged into a socket you can use, if that something works and hasn't electrocuted you yet, it seems reasonable to believe the plug is okay. Or use a multimeter to check your earth strap against a known ground before you wear it.

Either (a) this is a reasonable worry given the state of your electrics, in which case get your wiring checked by an electrician regardless, or (b) you're excessively worrying over nothing.

Or now I think about it, do you mean that you are worried that the fault is inside the wrist strap plug? In which case don't be, because the live/neutral prongs on that plug should be plastic, not metal, with no wiring at all.
