Electrical tingling sensation with a 2 prong power adapter - theoretical and experimental
Why people recommend it
A professor's explanation of why appliances can produce a tingling touch, attributed to transformer stray capacitance, which people cite to explain the effect and related sensor noise.
Watch for: The plug orientation point comes midway through
In their words
Swapping the power outlet might also work; here a Prof explains that: [video] He says the transform will have different stray capacitance due to windings depending on how the plug is inserted to the socket.
