A physiological response generated by an electric current traveling through the body is known as an electrical injury. Larger currents, on the other hand, cause tissue damage and can cause ventricular fibrillation or cardiac collapse. People are electrocuted by two main factors: voltage and resistance. The amount of voltage that reaches a person is determined by the circuit being used to supply power, while the resistance of the body determines how much current flows through it. If you connect a voltmeter to any part of the body, the reading will be low until something interrupts the path between the positive and negative terminals of the voltmeter. At this point, the meter will rise to high voltage immediately because there is no more resistance between those two points. A small wire has very little resistance compared to most parts of the body, so even a small current can cause injury or death. In general, people can withstand a certain amount of voltage before it causes injury or death. This threshold varies for different parts of the body and depends on many factors such as weight, size, and type of tissue. The higher the resistance of the body in ohms, the lower the current required to reach it. For example, a person could stand on one foot in the path of a high-voltage power line and not be injured because their body resistance is too low at about 10,000 ohms.
