Welding 101 Practice Test

Can humans conduct electricity?

No Only if damp Yes Only with protective gear

Correct Answer:

Yes

Explanation:

Electricity can flow through the human body because our tissues and bodily fluids contain ions that carry current. The skin’s outer layer acts as a resistance, so dry skin limits conduction, but it doesn’t stop it entirely. When skin is damp or there’s a direct electrical path through a wet contact, resistance drops and more current can pass through the body. This is why exposure to electrical sources can be dangerous: the amount of current that flows depends on the voltage and the body's resistance. Protective gear doesn’t enable conduction; it increases resistance and provides insulation, reducing the current that can reach the body. So, yes, humans can conduct electricity.
