While helping to design the newest class of internal defibrillators, your design team is tasked with testing the
viability of the new design to deliver the appropriate energy to the heart. An approximate schematic of the
charging circuit is below. Because the defibrillator requires around 2 J of energy for a low level shock, this must
be the maximum energy stored in the capacitors. When the switch is closed the capacitors begin to charge.
(a) What is the current that flows through the 100 Ω resistor immediately after the switch is closed when the
capacitors begin to charge. What is the current when the capacitors are fully charged?
(b) What is the required unknown capacitance needed to reach this maximum energy at full charge (without
(c) How much charge is on the plates of the capacitors when fully charged? V...
