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 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?
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...
