Question

Ask Your Teacher Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. What is the voltage across an 9.07-nm-thick membrane if the electric field strength across it is 8.76 MV/m?

Answer 1

The voltage across an 9.07-nm-thick membrane if the electric field strength across it is 8.76 MV/m is 0.079 V

Step-by-step explanation:

Given

Electric field (E) = 8.76 MV/m = 8.76 *
`10^(6)` V/m

Thick of the membrane = 9.07 nm = 9.07 *
`10^(-9)` m

Potential difference between uniform electric field plates

ΔVab = Ed

ΔVab = 8.76 *
`10^(6)` V/m * 9.07 *
`10^(-9)` m = 0.079 V
