In order to calculate that, we'd also need to know
Efflux via active transport
No. The negative ions stay within the cell (neuron).An action potential begins (rising phase) with an influx of sodium, a positive ion or cation. The rising phase ends (falling phase) with an efflux of positive ions (potassium). The membrane potential is stabilized again with the action of the ATP dependent sodium-potassium pump.
Subthreshold depolarization refers to a small increase in the membrane potential of a nerve cell that does not reach the threshold for generating an action potential. It is a graded response that occurs when the membrane potential of the nerve cell approaches but does not exceed the threshold for firing an action potential. Subthreshold depolarizations can summate or integrate within the cell to reach the threshold and trigger an action potential.
Since the concentration gradient is very large for potassium (where the concentration is much greater ( ~20-30X) inside the cell than outside the cell), reducing this concentration gradient by increasing the concentration of extracellular potassium would result in decreased efflux of potassium through leak channels. This decrease in efflux would result in immediate depolarization of the cell membrane, and would probably be sufficient to generate an action potential (if the depolarization met the threshold level of ~55mV). Now this would only apply to the first generation of an action potential, because if the cell were not able to restore its resting membrane potential (as in the case of increased XC potassium), no subsequent action potentials would be generated. Remember that eventually, equilibrium would be reached between the concentrations of potassium inside and outside the cell, meaning no net flux of those ions, meaning no membrane potential.
Calcium is primarily transported into or out of the cell using specialized protein channels called calcium channels. These channels allow calcium ions to move across the cell membrane, either into the cell (via calcium influx) or out of the cell (via calcium efflux). Additionally, calcium can also be transported into the cell by calcium transporters such as ATPase pumps.
The efflux of potassium ions is maintained by passive potassium channels.

sorry, i speak english.
speed of efflux = v = √2gh if height is doubled h=2h v=√2g(2h) =√4gh =√4√gh =2√gh v=2√gh

Depending upon the context, possible antonyms include: exodus, outflow, efflux, effluence, outpouring.
Velocity of propagation of rayleigh waves is smaller than that of body waves.The above gear ratio equation can be used to calculate the angular velocity of the large gear from the small gear.The above gear ratio equation can be used to calculate the angular velocity of the large gear from the small gear.Velocity dispersion curve thus produced is then used to calculate the material stiffness.An additional benefit was that the light weight permitted a higher muzzle velocity, reducing the time of flight.Velocityecise location of the initial stage of development of the ness pole must be linked to where tidal current velocities start to diminish.Velocity example of figure 3, tho, the sedimentary p-wave velocities are significantly lower than the basalt s-wave velocities.Velocity of recession with distance.R radial velocity the speed at which an object is moving away or toward an observer.Velocity vector, without change of direction.Ncs show slowing of conduction velocity across the elbow.Velocityeridional propagation velocities from high to low latitudes are less than 600 m/s.This may account for a large loss of rotational velocitythrough the millions of years.Velocity gradient depending on the relative movement of the bearing surfaces.A cone fitted at the chimney exit to increase efflux velocity should be permitted.The differences in lava composition between the stratigraphic groups affect the average seismic velocity of each group.Velocity v will also shrink.For very low e / n, the drift velocity is proportional to e / n.The rotation curve is a plot of the orbital velocity of the clouds around the galactic center vs. their distance from the galaxy center.Velocity rifle.

By increasing the extracellular K+ there is efflux and also influx into the cell which increases the tendency of the cell to depolarize.
