Modern air cathodes consist of a reactive layer of carbon with a nickel-grid current collector, a catalyst ( e . g ., cobalt ), and a porous hydrophobic PTFE film that prevents electrolyte leakage.
12.
Because the grid is negatively charged relative to both the anode and the screen grid, it repels any secondary electrons back to the anode preventing them from contributing to the screen grid current, and to any negative resistance characteristic.
13.
Although this may be mitigated to some degree by taking the resistor to the top of the tuned circuit ( i . e . in parallel with the capacitor ) and through the coil to earth, or by circuit design and component optimization, forward grid current will still load the input signal ( and reduce the Q of the tuned circuit ).
14.
A "'grid-leak detector "'is a thermionic valve ( UK, Australia, NZ etc . ), or vacuum tube ( USA ), circuit used in older vacuum tube grid bias voltage necessary for proper operation from grid current that occurs in all vacuum tubes due to electrons attracted to the grid during the positive part of the RF cycle.
