Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the basics.

I’ve used hybrid capacitor and NiMH capacitors in the past from Varta. Charging characteristics of a capacitor but can sustain voltage like a battery. Measured in farads such as 90F 4.2V.

The equivalent circuit used for conventional capacitors can also be applied to ultracapacitors. The circuit schematic in Fig. 2 represents the first-order model for an ultracapacitor.

The circuit uses minimum external components. For touch plate, you can use a simple copper plate of 1cm×1cm or even the end of the lead wire. Touch plate is coupled to the touch detector through 820pF ...
