I have two physics problems that I'm not sure how to do, can someone help me? 1) 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 1.6 ms. (a) How much charge moves during this time? (b) How many electrons pass through the wires connected to the patient? 2) A resistor is connected across the terminals of a 9.0-V battery, which delivers 2 x 105 J of energy to the resistor in 4 hours. What is the resistance of the resistor? Should I use the equation delta q=I(delta t) for both these problems?
