    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 ?....

    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 defibrillator being used on a patient has an RC time constant of 9.5 ms due to the resistance of the patient's body and the capacitance of the defibrillator. 1. If the defibrillator has an 9.5 μF capacitance, what is the resistance of the path through the patient in kΩ? (You may neglect the capacitance of the patient's body and the resistance of the defibrillator.) 2. If the initial voltage is 11 kV, how long does it take to...

    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...
