{'electric resistance': [0, 0, 1, 0], 'magnitude': [0, 0, 3, 10], 'human body': [40, 2, 44, 29], 'ohm': [0, 0, 1, 2]}
The human body, when dry, has an electric resistance on the order of magnitude of 10^4 ohm (10,000 ohm). This resistance can vary depending on factors such as skin moisture, contact area, and individual characteristics. Dry skin offers a relatively high resistance to the flow of electric current due to its insulating properties.
The resistance of the human body plays a significant role in determining the effects of electric shocks and electrical safety measures. Higher resistance limits the current flow through the body, reducing the potential harm caused by electric shock. However, it`s important to note that wet or moist conditions can significantly decrease the body`s resistance and increase the risk of electrical injury.
