Hi all,
I recently did the water level circuit . I used a Darlington transistor in my water level circuit as I needed more current to control my 12 v relay. The thing that I noticed is that when I dropped one probe into a bucket of water and held one in my hand and touched water with my other hand , I felt a mild shock. But when I measured it using my multimeter it read only 12 v which was the power supplied from my 12 v adaptor( regulated voltage) .
What could be the reason?
Please help.
I didn't find the right solution from the Internet.
