What will be the effect when a current of 20 to 50 mA passes through the human body?

What will be the effect when a current of 20 to 50 mA passes through the human body? Correct Answer <span style="">Severe muscular contraction (Breathing will be difficult)</span>

Effect of electrical shock on the human body:

  • The severity of injury from electrical shock depends on the amount of electrical current and the length of time the current passes through the body.
  • The amount of internal current a person can withstand and still be able to control the muscles of the arm and hand can be less than 10 mA.
  • Currents above 10 mA can paralyze or “freeze” muscles.
  • The current up to 50 mA through the human body can cause severe muscular contraction which produces breathing problems.
  • Currents greater than 50 mA cause ventricular fibrillation. This condition will cause death within a few minutes unless a special device called a defibrillator is used to save the victim.
  • Heart paralysis occurs at 4 A, which means the heart does not pump at all. Tissue is burned with currents greater than 5 A.

"Too often we try to solve human problem with non-human tools and in terms of non-human data. It is my simple thesis that a human problem requires a human solution. First we have to learn to recognise a human problem when we see one; and second, upon recognising it, we have to learn to deal with it as such and not as it were something else. A human problem to be brought to a human solution requires human data and human tools". Who said this?

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. What do we see when we look at an object?
