Chapter 7, Problem 10C
A defibrillator sends approximately 0.1 C of charge through a patient’s chest in about 2 ms. The average voltage during the discharge is approximately 3,000 V Compute the average current that flows, the average power output, and the total energy consumed (Note: Only a small portion of this current actually flows through the heart in a typical fibrillating procedure. Much of the charge is diffused throughout the patient’s thoracic cavity).

The internal energy of the water in a container is increased by 440 kJ by means of an electric heater. Since the electric current passing through the heater is 5 Amperes and the operating time of the heater is 13 minutes and 20 seconds, how many volts is the voltage applied to the heater?
What explains the difference in energy delivery when the rate of discharge changes in a battery? For example, a lithium coin battery has a rated capacity of 240 mAh and a voltage cutoff of 1.6V. If we compare two rate of dischange, 3 mA vs. 0.5 mA, the difference in energy delivery is 0.1Wh.
Two capacitors of capacitance 3C and 5C (where C = 0.19 F) are connected in series with a resistor of resistance R = 9.5 Ω.
If the circuit was charged by a 10.0 V source how much total charge (in C) did both capacitors have in them to begin with?
