This is an analogy to capacitive and resistive current
Air is blown in the balloon (representing the injection of current)
Some air excapes, depending on the internal pressure (like
resistive current that depends on electrical potential, V)
Some air inflates/deflates the balloon (like capacitive current
that adds/subtracts charges from the membrane when V changes)
- When the flow increases, initially most of it inflates the balloon,
until the pressure raises the leak up to the same level as the inflow.
- When the flow decreases the pressure also decreases: deflation sustains
most of the leak, which gradually declines back to the initial condition
following the decline of pressure.
- while inflating, part of the inflow inflates: leak < inflow
- while deflating, deflation adds to the inflow: leak = flow+deflation
