Measure JFET drain current with a current mirror - part 2: build and measure

Measure JFET drain current with a current mirror - part 2: build and measure/members-area/b/blog/posts/measure-jfet-drain-current-with-a-current-mirror---part-2-build-and-measureI learned a trick from w2aew : how to measure current if you don't have a current probe.He's using a N-channel JFET as example. I adapted it to a P-channel type - the J176. This second post is the practical part. No talk and simulation.
