Question

An important use of capacitors is in defibrillators. A defibrillator works by discharging a capacitor across a human chest, causing a current to pass through te heart. That current can reset erratic heartbeats, allowing the heart to function properly again. One defibrillator manufacturer sells a capacitor with a capacitance of 202 μF that is rated at a voltage of 1.9 kV . The manufacturer claims that these capacitors can provide peak currents of up to 300 A .

With the parameters given by the manufacturer, how long would it take to discharge 99% of the charge on this capacitor (when using it on a person)?
