Question

0 The inner a potential difference of about 0.081 V exists across the membrane. The thickness of the cell membrane is 7.40 × 10-9 m. What is the magnitude of the electric field in the membrane? V/m Additional Materials Section 194 14 -1 points Cu10 19.P.O3S My Notes Aak your Teacher A spark plug in an automobile engine consists of two metal conductors that are separated by a distance of 0.88 mm. When an electric spark jumps between them, the magnitude of the electric field is 5.60 x 10 V/m. What is the magnitude of the potential difference AV between the conductors? Additional Materials Section 194

Explanation / Answer

13) the magnitude of the electric field will be determined by the formula V=E*d or E= V/d

here V=0.081 V and d=7.40*10^-9 m using the values

E= 0.081/7.40*10^-9= 10945945.95 N/C
