Usually, one would simply go with the fuse or nameplate current rating of the radio.  All of these things affect it if you're designing a power supply, but that's a pretty complex task (especially these days, with coils so out of favour in general) and is perhaps more suited to element 4.  At this level I'd be expecting people to be able to match current and understand how to supply enough of it, and what happens if you don't, but I care more about wire gauge than about this for element 2.

Welcome to the ham radio question pool development site.

Answer a question to give your feedback on how it could be improved, why it's not right, or why it should go.

You can vote questions up to indicate they're great, or down to indicate they should not be given.

To propose questions and have them discussed here, use the "Suggested" category within each element.

Feedback can be used by VECs to decide on questions to exclude, and will be forwarded to the NCVEC QPC on a regular basis.
