It’s not electricity, exactly, but it is a higher voltage that is different from the average of everything around it. Electricity needs a closed loop to flow, and breaking open the loop with a switch means that no electricity flows, but the voltage of the live line goes up and down, creating an electric potential with anything that might be at a different voltage, if a conductor touches both.
Peppers, tomatoes, and potatoes have basically spread everywhere at this point. Most Asian and African cultures have readily incorporated those into their own food traditions to where it’s hard to imagine how those cuisines were like before crop exchange with the New World.
