What is the frequency of mains electric noise in the uk?

Ionising radiation can remove an electron from an atom/ molecule that it comes into contact with. This will turn that atom/molecule into a positive ion but but that doesn't mean it forms an ionic bond. Yes you are correct that ionic bonding occurs between metals and non metals.

I know that in a step down transformer the voltage is reduced and therefore current has to increase because P=IV. But potential difference is what drives the current so when the voltage decreases it seems strange for the current not to decrease too. Another why of putting it is if both coils...
