A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 16 A of current through the torso of a person in 2.5 ms. (a) How much charge moves during this time? (b) How many electrons pass through the wires connected to the patient?
Here,
a) for the total charge
total charge = current * time
total charge = 16 * 0.0025
total charge = 0.04 C
total charge moved is 0.04 C
part b)
number of electrons pass = charge/e
number of electrons pass = 0.04/(1.602 *10^-19)
number of electrons pass = 2.5 *10^17
the number of electrons passing is 2.5 *1017

A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 19 A of current through the torso of a person in 2.3 ms. (a) How much charge moves during this time? (b) How many electrons pass through the wires connected to the patient?
A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 21 A of current through the torso of a person in 1.8 ms. (a) How much charge moves during this time? C (b) How many electrons pass through the wires connected to the patient? electrons
A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 18 A of current through the torso of a person in 1.7 ms. (a) How much charge moves during this time? (b) How many electrons pass through the wires connected to the patient? Need the full answer for b. Not expessed as x10^
(a) A defibrillator passes 13.0 A of current through the torso of a person for 0.0400 s. How much charge moves in coulombs? (b) How many electrons pass through the wires connected to the patient?
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 heart defibrillator is used to enable the heart to start beating if it has stopped. This is done by passing a large current of 12 A through the body at 21 V for a very short time, usually about 3.4 ms . What power does the defibrillator deliver to the body? How much energy is transferred?
That needs a defibrillator passes 12A current through the torso person for point 04 seconds how much charge moves
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?
