... C = o A/d = A/4Kd = (5E-4)2/[4(9E9)(1E-4)] ≈ 7E-14F Even with a 100kΩ resistor, this gives RC = 7E-9 seconds and very little charge on the “capacitor”. This means you would never notice the charge or discharge behavior of the open circuit, it’s over too quickly and little charge is transferred. ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
