WebThe reason for this is that electrons are negatively charged. They are in a state of high potential when at the negative end and low potential at the positive end. Before physicists knew that electrons moved, they assumed that positive charges were doing the moving. Negative differential resistance devices are widely used to make electronic oscillators. In a negative resistance oscillator, a negative differential resistance device such as an IMPATT diode, Gunn diode, or microwave vacuum tube is connected across an electrical resonator such as an LC circuit, a quartz crystal, dielectric resonator or cavity resonator with a DC source to bias the device into its negative resistance region and provide power. A resonator such as an LC circuit is "alm…
