help finding the voltage in a uniform E-field

mercredi 2 juillet 2014

1. The problem statement, all variables and given/known data

Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. What is the voltage across an 8.67-nm-thick membrane if the electric field strength across it is 9.16 MV/m? You may assume a uniform E-field.



2. Relevant equations



E=-Vd



3. The attempt at a solution



.00912V/m=-V/(8.67e-9m) =7.9e-11 V
