I live in India, the voltage supply in houses is 220V.
Sometimes, for example in my washing machine, when it is full of water and I put my hand in it, I get a feeling like a thorn/tiny nail is piercing my finger near nails. Same happens if some liquid is touch inside freezer.
Sometimes it happens when I even touch the body of fridge.
It doesn't give a shock, but I'm serious about it. Is it a low level of shock or is it something else?
It happens when the appliances are plugged in.
