An automated external defibrillator (AED) is designed to deliver a rapid, controlled pulse of electrical energy through a patient's chest to restore normal heart rhythm.
During a therapeutic shock, a potential difference of 1600 V is applied across the electrodes.
A total charge of 0.080 C is transferred through the chest tissue in a time interval of 4.0 ms.
Calculate the electrical resistance of the pathway between the electrodes.
