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 2.0 ms.
a) How much charge moves during this time?
many electrons pass through the wires connected to the patient?
Q = I*t, which means
Divide the Charge Q by the electron charge, e, to get the number of electrons.
Look up the electron charge if you don't know it. It is a number you should memorize. You should also memorize the formula.
a) 0.036 C
