An electric shock can result in anything from a slight tingling sensation to immediate cardiac arrest. The severity depends on t
he amount of current flowing through the body, the current's path through the body, the length of time the body remains in the circuit, and the current's ________.
The current's frequency which is measured in hertz (Hz) refers to the number of times the repetition of one cycle of the waveform occurs per second.
The frequency of mains electricity can repeats 50 times per second, that is its frequency is 50Hz.
The function of the frequency is to alternate the current between high and low current; and the lower the frequency alternating current, the more dangerous.
Therefore, an electric shock can be very fatal when the there is a low frequency alternating current.
Blood is capable of passing many diseases and sicknesses so washing your hands is good for the doctor and the patient to deter any germs, and putting on gloves is good for the doctor and patient to not pass diseases through open sores or cuts on each other :D
