Di ko alam mga sis kung tama tong pinagposan ko ng topic . Ask ko lang kung may idea kau dun sa Ion Pump at Grid. Nkalagay kasi meters (digital) kv ung voltage 0 ung current. Panu nangyari un voltage exist without current? tinry ko na kasi gingoogle kaso ala ako mahanap na sagot. Hope someone can help me.

TIA

Ion pumps operate with high voltages like in static electrical fields, voltage can exist without current. Same as in a capacitor, battery. Ayun ba ang tanong mo?

Malapit na dun sis, Why ala siyang current pati ung grid? Sa tv tx ko nakita sis eh..

in a vacuum tube wherein there is a heated cathode as source of electrons, the grid as long as it is biased negative with respect to the cathode terminal will have a voltage without current.........

saan mo nag aaply ung principles na ito? Gaya po ba ung mga old oscilloscopes na gumagamit ng static deflection? meron po kasi ako oscilloscope gamit shop, wala sya deflection yoke.

Thanks sir tony, points for u, tnx din mga sis, parehas pala sa vacuum un, na research ko na finally here it is...

If the anode potential is reversed, and made negative with respect to the cathode it will repel the electrons. No electrons will be emitted from the anode as it is not hot, and no current flows. This means that current can only flow in one direction. In other words the device only allows current in one direction, blocking it in the other. In view of this effect, the inventor of the diode vacuum tube, Professor Sir Ambrose Fleming called it an "oscillation valve" in view of its one way action.
