What is the membrane length constant of a cell with membrane resistance r_m = 1 $\Omega$ cm and cytoplasmic resistance r_i = 100 $\Omega$/cm?

Question

Quizplus · Accepted Answer

The membrane length constant, λ, is given by the square root of the ratio of the membrane resistance (r_m) to the cytoplasmic resistance (r_i). Given r_m = 1 Ω·cm and r_i = 100 Ω/cm, λ = sqrt(r_m / r_i) = sqrt(1/100) cm = 0.1 cm = 1 mm.
