Question

What is the voltage across an 8.00 nm–thick membrane if the electric field strength across it is 5.50 MV/m?

Answer 1

0.044 V

Step-by-step explanation:

E = Electric field =
`5.5* 10^6\ V/m`

d = Thickness of membrane = 8 nm

When the electric field strength is multiplied by the membrane thickness we get the voltage

Voltage across a gap is given by

`V=Ed\\\Rightarrow V=5.5* 10^6* 8* 10^(-9)\\\Rightarrow V=0.044\ V`

The voltage across the membrane is 0.044 V
