A
(b) What is the total power supplied to the two resistors?
W
2) A defibrillator is used during a heart attack to restore the heart to its normal beating pattern (see Section 19.5). A defibrillator passes 17 A of current through the torso of a person in 1.9 ms.

C
(b) How many electrons pass through the wires connected to the patient?
electrons
