What are the factors associated with electrical shock?
Damage to human body is basically due to the magnitude of the current and not the voltage. But it may be understood that the voltage and the resistance of the body determines the amount of the current flow. The basic factors are magnitude of the current, the flow route and the duration of the current flow. If it is an a.c. circuit, the frequency is also important as it could affect the function of the heart, for example. Damages can be due to thermal and non-thermal effects. Thermal effect produces burns and non-thermal effect produce electrical breakdown of muscles and nerve cells.
