5. Defibrillator machines are used to deliver an electric shock to the human heart, to resuscitate a heart that has stopped beating. It is estimated that a current as low as 18 mA through the heart is required to resuscitate. Using
95 kN as the resistance, determine the output voltage a defibrillator needs.
