Question

How many volts of energy can a human body survive?

Answer 1

Hint: Voltage, commonly called electric potential difference, is measured as the difference in the electric potential between two points. It can be defined as the work required per unit of charge to displace a test charge from one point to another. Its SI unit is joules per coulomb, or simply volt.

Complete answer:
Voltage is the force of the electric power passing through a conductor. When the flow of current is passed through the body, it clamps the heart and can even cause the death of the person. This flowing current is basically measured through its voltage and the resistance of the circuit. Our body is developed in a way that it can resist electric current if the voltage is not sufficient to cause a shock. Thus, in the absence of high voltage, flowing current cannot flow through the body or cause injury or death. For example, a shock of 20,000 volts is passed through the body but the current is extremely low and duration is short, the shock would be harmless. Similarly, if the voltage is very low (say, 10 V) and the current rate is high, still the shock will be harmless. Thus, a voltage greater than 50 volts is sufficient to drive a lethal current through the body if sufficient current is provided.

Note: Voltage alone cannot be considered as a factor in the severe electric shock. Current and some other minor factors also contribute to it. Current is defined as the rate of electrical flow and is measured in Ampere. Other factors contributing to it are the duration of shock and the point from where it entered the body.
