Dear sir/ madam,

Nowadays I’m trying to make an efficient power saving wireless battery recharger for a mobile phone. Sadly, my teacher for my PWS doesn’t know, what kind of value’s I have to use in my system. Therefore I’m contacting you to give me advice with these kinds of experiments. For this experiment, I use only transistors, capacitors, resistors and so on. I succesfully managed to make the wireless power transmittor. Hopefully, it will not be too much work. By the way, I have to do my PWS in English, but you can also answer in Dutch.

Yours sincerely,

T.N.T.
