The cathode anode and grid are all aligned parallel to one another. This planar configuration corresponds to the conventional symbol for a triode. A circular metal plate attached as a backing to the filament ensures that the electric field between the anode and cathode is uniform.\u003cbr\u003eThe triode allows basic experiments to be performed using the Edison effect (thermionic effect), determining the negative charge of electrons, recording triode characteristics and generating cathode rays (model of an electron gun). It also allows investigating the technical application of a triode as an amplifier and generating undamped oscillations in LC circuits.\u003cbr\u003e\u003cbr\u003eSpecifications: ..\u003cbr\u003eFilament voltage UF :\tmax. 7.5 V AC\/DC\t \t \u003cbr\u003eFilament current IF :\t3 A approx.\t \t \u003cbr\u003eAnode voltage UA :\tmax. 500 V\t \t \u003cbr\u003eAnode current IA :\t( @ UA = 400 V, UF = 6.3 V DC )\u003cbr\u003e \tGrid voltage UG :\tAnode current IA\u003cbr\u003e \t0 V\t \t0.4 mA  approx.\u003cbr\u003e \t+8 V\t \t0.8 mA  approx.\u003cbr\u003e \t-8 V\t \t0.04 mA  approx.\u003cbr\u003eTotal length:\t300 mm approx.\t \t \u003cbr\u003eGlass bulb:\t130 mm Ø,  approx.","brand":"3B Scientific Teltron","offers":[{"title":"Default Title","offer_id":49419051401493,"sku":"3BS1000647","price":1529.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0857\/4897\/3845\/files\/U19151_01_1200_1200_Triode-D-Vacuum.jpg?v=1761020761","url":"https:\/\/unitedsupplycorp.com\/products\/triode-d-vacuum","provider":"United Supply Corp.","version":"1.0","type":"link"}
