[2/6 Points] DETAILS PREVIOUS ANSWERS The electrical signals to the heart are typically coordinated to create a wave of compression that travels across the heart and pumps the blood through the heart chambers. If these signals get misaligned, the bits of the heart muscle vibrate independen called fibrillation and can quickly lead to death. If the situation is caught in time, passing a jolt of current through the heart can realign the electrical signals in the heart and start it beating again. The device that delivers this current is a defibrillator. T A battery takes perhaps half a minute to charge this capacitor. A typical defibrillator capacitor might have a capacitance of 51 /F and is charged by a battery to a potential difference of 4210 V. 1. What is the magnitude of charge stored on one of the capacitor plates when it is fully charged? 1Q1 = 232100 X MC 2. The energy stored in a capacitor is 1/2|Q| |AVI. How much energy (electric potential energy in this case) is stored in the defibrillator's capacitor when it's fully charged? Ue = 489.73 X The energy in the capacitor is delivered by placing paddles on either side of the victim's heart as shown in the figure. The defibrillator delivers the charge stored in the capacitor through the paddles, hopefully resetting the heart so it can begin beating 3. The charge is delivered in a sudden pulse that lasts about 100 ms. What is the average current flowing through the body? = 214710 X A 4. What is the rate at which the energy stored in the capacitor is transferred to the body? This is the average power output of the defibrillator. P> = 4,519.6 W 5. As the charge drains from the capacitor, its potential difference decreases. What is the average potential difference of the capacitor? This is the potential difference needed to deliver the average current at the given rate. = 2100 6. What is the effective resistance of the body along the path that the current takes?

If these signals get misaligned, the bits of the heart muscle vibrate independently and as a result do not move blood. This situation is h. If the situation is caught in time, passing a jolt of current through the heart can realign the electrical signals in the heart and start it beating again. The device that delivers this current is a defibrillator. The central component of a defibrillator is a big capacitor. rge this capacitor.
