Kadang kita berpikir kenapa tegangan 220 V dirumah bisa mengakibatkan kematian, sedangkan tegangan baterai 12 V tidak apa apa bila dipegang. Nah, hal ini disebabkan tahanan tubuh kita terhadap listrik yang apabila diukur adalah sebesar 1200-5000 Ohm . Maka dengan rumus dibawah ini, bisa didapatkan berapa besar arus listrik yang mengalir di tubuh manusia. Arus listrik = Tegangan : Tahanan. Jantung sebagai organ tubuh yang paling rentan terhadap pengaruh aliran arus listrik merasakan dalam empat ...
