7. t is the current that causes the shock In practice the higher the voltage the higher the current will be and the higher the shock But there is another thing to consider and it is resistance When the resistance in Ohms is high between two poles the current will be low and vice versa All three of these voltage current and resistance are important in determining the effect of an electrical shock However the severity of a shock primarily determined by the amount of current flowing through a person A person can feel a shock because the muscles in a body respond to electrical current and because the heart is a muscle it can affect when the current is high enough Current can also be fatal when it causes the chest muscles to contract and stop breathing At what potential is current dangerous Well the first feeling of current is a tingle at 0 001 Amp of current The current between 01 Amp and 0 2 Amp is fatal Imagine that your home fuses of 20 Amp can handle 200 times more current than is necessary to kill How does resistance affect the shock a person feels A typical resistance between one hand to the other in dry condition could well over 100 000 Ohm If you are playing on stage your body is perspiring extensively and your body resistance is lowered by more than 50 This is a situation in which current can easily flow Current will flow when there is a difference in ground potential between eguipment on stage and in the P A system Ple
