What can occur as a result of a shock above 1A?

When a current flows through the human body, particularly at levels greater than 1 ampere, it can have serious physiological effects. One significant outcome of such a current is the heart entering a state of fibrillation.

Fibrillation is a condition where the heart's electrical activity becomes chaotic, leading to ineffective or disorganized heart contractions. This can result in the heart being unable to pump blood effectively, which poses a grave risk of cardiac arrest. Electrical shock that causes a current above this threshold can disrupt the normal rhythm of the heart's electrical impulses, directly leading to fibrillation.

This effect highlights why understanding electrical safety and the implications of electric shock is critical for electricians and other professionals who work with electrical systems. Awareness of the dangers associated with different current levels helps in the implementation of proper safety measures and protocols to protect individuals from potentially fatal electrical incidents.
