It is known that the amount of current needed to flow through a human being in order to cause them to have ventricular fibrillation (heart attack) is about 100 mA.
What is the minimum voltage (in volts) that will cause a person who has a body resistance of \(1723\ \Omega\) to have ventricular fibrillation?
