Final answer:
The conductance ratio of voltage versus time exposed is not a determining factor for the severity of an electric shock. Key determining factors include the amount of current, the path taken by the current through the body, the duration of the exposure, and the frequency of the current.
Step-by-step explanation:
Factors Determining Electric Shock Severity
The severity of an electric shock is influenced by several factors. Determining factors include the amount of current (I), the pathway of the current through the body, the duration of exposure to the current, and the frequency of the current (f = 0 for DC). Contrary to part of the question, conductance ratio of voltage versus time exposed is not a listed determining factor for the severity of an electric shock. Instead, the severity is largely dependent on the actual magnitude of current passing through the body and not the ratio of voltage to time.
For instance, a person with dry skin may have a high resistance and experience a relatively harmless shock from a contact with a 120-V AC source, resulting in a 0.6 mA current. However, if the same person is wet, their resistance drops significantly, leading to a dangerous current of 12 mA, which is above the threshold where one may not be able to voluntarily release the electric source.
