On the Three-Components-in-One Volatile Capacitor

The first author has realized a volatile capacitor as two partially-contacting resisters with differential current which can take both positive and negative capacitance values. We refer to this as a two-resistor structure capacitor (TRSC). Experimental results on the real device appeared in[1] and will soon appear in[2] and in papers in preparation. This note provides some plausible elucidations and additions to the underlying philosophy and reasoning of these and forthcoming papers. In order to make this surprising device more intelligible to a wider audience, we shall explain its use as a three-components-in-one device among many other practical uses. We shall also give a speculative explanation of the virtual differential current in TRSC from the point of view of the governing role of the tunneling current.
