A
dynatron oscillator is an electronic circuit that uses negative resistance to keep an LC tank circuit oscillating. In theory, if an

dynatron oscillator thus operated on the same principle of negative resistance as the tunnel diode oscillator many years

dynatron effect. Placement : In its simplest form, a
