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...

Explain why capacitance ?C depends neither on the stored charge ?q nor on the potential difference ?V between the plates of a capacitor. Capacitance is determined only by the physical properties of the capacitor. The stored charge ?q and the potential difference ?V are independent of the size and shape of the capacitor. The net charge on a capacitor is zero, and therefore the potential difference ?V cancels. The stored charge ?q is inversely proportional to the potential difference ?....

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 the heart. That current can reset erratic heartbeats, allowing the heart to function properly again. One defibrillator manufacturer sells a capacitor with a capacitance of 196 mu F that is rated at a voltage of 2.2kV. The manufacturer claims that these capacitors can provide peak currents of up to 300A. Assuming...

A 11.6 μF capacitor in a heart defibrillator unit is charged fully by a 12000 V power supply. Each capacitor plate is connected to the chest of a patient by wires and flat "paddles," one on either side of the heart. The energy stored in the capacitor is delivered through an RC circuit, where R is the resistance of the body between the two paddles. Data indicate that it takes 76.3 ms for the voltage to drop to 20.5 V...

A heart dysfunction that can cause death is ventricular fibrillation. This is an uncoordinated quivering of the heart as opposed to regular beating. An electric shock to the chest can cause momentary paralysis of the heart muscle, after which the heart will sometimes start organized beating again. A defibrillator is a device that applies a strong electric shock to the chest over a time of a few milliseconds. The device contains a capacitor of several microfarads, charged to several thousand...

A defibrillator passes a brief burst of current through the heart to restore normal beating. In one such defibrillator, a 59.5 µF capacitor is charged to 5.6 kV. Paddles are used to make an electrical connection to the patient's chest. A pulse of current lasting 1.0 ms partially discharges the capacitor through the patient. The electrical resistance of the patient (from paddle to paddle) is 226 Ω. (a) What is the initial energy stored in the capacitor? J (b) What...
