However, there are no capacitors described in this circuit, and so we're looking at parasitic capacitance, less than picofarads, which is to say, a billion times less than that.

Values available range from very low ( picofarad range; while arbitrarily low values are in principle possible, stray ( parasitic ) capacitance in any circuit is the limiting factor ) to about 5 kF supercapacitors.
13.
In biological organisms, ion channels regulate the flow of ions ( for example, sodium, calcium, potassium ) across the picofarad ), that is, current divided by capacitance, a de facto measure of membrane area.
14.
The capacitance of a few centimeters of wire ( insulated or in air ) is going to be somewhere in the very approximate neighbourhood & ndash; give or take a couple orders of magnitude & ndash; of one picofarad.
15.
Ordinary lamp cord has a capacitance of 10 20 pF per foot, plus a few picofarads of stray capacitance, so a 50 foot run ( 100 total feet of conductor ) will have less than 1 percent capacitive loss in the audible range.

Fortunately, your capacitance is pathetically tiny ( on the order of a hundred picofarads ) so the total charge you can accumulate from a carpet is only enough to give you a nasty tingle and not cause lasting harm . talk ) 01 : 49, 22 June 2006 ( UTC)

The 6AV6 anode-grid capacitance is 2 picofarads ( pF ), the 7768 has a value of 1.7 pF . The close electrode spacing used in microwave tubes " increases " capacitances, but this increase is offset by their overall reduced dimensions compared to lower-frequency tubes.
