Question

a human being can just feel the effect of electric current is in the order of​

Answer 1

Answer:

Electric current is defined as the rate of flow of negative charges of the conductor. For an electric current to occur, it has to be conducted through a material. When the flow of electrons provided by electricity finds a resistance, it results in a dissipation of energy in the form of heat. If there is an excessive amount of heat generated, the tissue may be burnt. Physiologically, the difference between a normal burn and a burn caused by electricity is that electricity has the ability to burn tissue beneath the skin, even burning internal organs without apparent external evidence of it

The contact with electric current can have various effects on the human body such as pain, burns or even death. There are many factors which affect the way the body interacts with current, such as the skin resistance, the voltage, the lenght of time of contact,the amount of electric current and its intensity. The body is extremely sensitive to the effects of electric current, that´s why this scenario can lead to a variety of outcomes. Firstly it disrupts normal operation of our nervous and muscular systems. The other reason when current passes through your body, it is transformed into thermal energy. This can cause serious burns, both inside your body and on your skin.

Currents of about 10 mA can cause a very painful shock. The longer the current continues to pass through you, the worse it gets. More heat is generated and the damage to your body increases, so the inability to let go can cause some serious problems. Currents above about 100 mA are almost always fatal unless immediate medical attention is provided.

The amount of current passing through a human body depends on two things: the voltage supplied by the source and the electrical resistance of your body. The amount of electric current that flows through the body determines various effects of an electric shock. Most current-related effects result from heating of tissues and stimulation of muscles and nerves.
