A defibrillator delivers a jolt of electrical energy to restart a heart that is either stopped or undergoing ventricular defibrillation -- a rapid irregular beating. This energy is supplied by a charged capacitor. Consider a 265 μF capacitor charged to 2270 V in a defibrillator. A 4000 V power supply is used to charge the capacitor through a 36.7 kΩ resistor. If the capacitor is initially uncharged, how much time does it take to charge the capacitor to 2270 V?

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^

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 independently and as a result do not move blood. This situation is 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...

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...

You are tasked with designing a defibrillator with the following specifications: a) The defibrillator is modelled as a simple 1st order LTI system. The resistor in the charging circuit is 20k ohm. b) Charging time (from “empty”) is no more than 4 s from the moment the “charge” button is pressed to be within 2% of full charge value. c) The system allows the delivery of either 50, 75 or 125 J of energy to the patient. d) The patient...

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...

Suppose the battery on your phone delivers a current of 0.770 mA (that's milliAmperes) over a time of 3.00 hours. What is the total charge that flows out of the battery during this time? How many electrons flow out of the battery during this time?
