Nerve cells communicate to each other by acting as ”transducers” creating electrical signals (very small voltages and currents) in response to the input of certain chemical compounds called neurotransmitters,
Pure water is an electrical insulator, but with even a little added salt, it becomes an excellent conductor. Since humans are mostly water, we are also good conductors of electricity, which is why touching someone experiencing anelectric shockcauses the toucher to experience the same shock. In ...
If the duration were less than 1 s, greater currents could be tolerated without such adverse reactions. Electric shock accidents are most common on low-voltage systems and are usually subdivided into two categories of direct contact and indirect contact shocks. A direct contact shock occurs when ...
Uncertainty is the second condition in which a stress response is strongly elicited. Scientists tried to test the response to uncertainty by administering electrical shocks of different intensities (but still relatively mild) to animals. What researchers found was that the intensity of the shocks did ...
Capacitors are devices which store electrical energy in the form of an electric field. The process is quite similar to the way mechanical springs store energy in the form of elastic material deformation, to the extent that the math describing both is quite similar, save for the variables used....
The problem with this design is that all shocks or vibrations close the circuit in the same way. The brain has no way of measuring the intensity of the jolt, which results in a lot of false alarms. More advanced sensors send different information, depending on how severe the shock is. ...

(AED) machines are large and stationary, very old and not portable compared to the modern one that are small, portable and gives guidance when applying to a cardiac arrest patient or arrhythmia patient. Although those defibrillators produce the same electrical shocks as the modern defibrillator, ...

Localized pain, or pain you can point out to a specific area of the body Referred pain, or diffuse pain in a region Numbness A burning sensation, tingling, a feeling of “pins and needles,” or “electrical shocks” Fear not – this condition usually isn’t permanent. Signs and...
