Answer #1

almost right. 19 C/s x 0.023 s = 0.437 C. That is how much charged moved during that time.

To get the number of electrons divide 0.437 C by 1.9 x 10-19 C / electron. That is a lot of electrons :)

    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...

    A defibrillator passes a brief burst of current through the heart to restore normal beating. In one such defibrillator, a 40.6-μF capacitor is charged to 5.90 kV. Paddles are used to make an electric connection to the patient’s chest. A pulse of current lasting 1.00 ms partially discharges the capacitor through the patient. The electrical resistance of the patient (from paddle to paddle) is 240 Ω. What is the initial energy stored in the capacitor?

    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...

    During ventricular fibrillation the heart muscles contract randomly, preventing the coordinated pumping of blood. A defibrillator can often restore normal blood pumping by discharging the charge on a capacitor through the heart. Paddles are held against the patient's chest, and a 6.3 ×10−6 F charged capacitor is discharged in several milliseconds. If the capacitor energy is 270 J, what potential difference was used to charge the capacitor?

  • In comparing wires of identical shape and carrying the same current but made of different metals,...

    In comparing wires of identical shape and carrying the same current but made of different metals, is the drift velocity in each wire inversely proportional to the number density of charge carriers? No. The drift velocity is the same for all conductors. Yes. To have the same current from k times as many carriers, it takes k times the drift speed. No. The drift velocity is directly proportional to the number density of carriers. Yes. To have the same current...
