away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
