What influences the amount of body current experienced by a person?

The amount of body current experienced by a person is primarily influenced by both the voltage applied and the individual's body resistance. Voltage serves as the driving force that pushes the electrical current through the body's tissues. The body resistance, which can vary significantly from person to person, depending on factors such as moisture on the skin, contact area, and the physical condition of the skin, acts as an opposing force to the current flow.

When voltage is applied, Ohm’s Law becomes relevant, stating that current (I) equals voltage (V) divided by resistance (R). Therefore, the relationship between voltage and body resistance directly determines how much current flows through the body. A higher voltage could increase the current, while increased resistance would limit it.

Other factors like the environment can affect resistance, such as humidity, but ultimately, it's the interplay between voltage and body resistance that dictates the level of current flowing through a person. This combination makes it crucial to consider both elements when assessing electrical safety and the impact of electrical exposure on the human body.
