What is positive and negative grid current.

[Alan0354]

What direction is +ve ande -ve grid current?

In another word, if it is positive current, does that mean current flow OUT of the grid, the grid will get move positive because the current will develop a positive voltage across the grid resistor and make the grid more positive?

That's a good article, It really explain RDH4. RDH4 is very good, but the writing is not particularly clear. I kept thinking +ve current is grid sourcing current and that really confused me.
