1-A Pacemaker is a device that is implanted in the body and it helps to control the heartbeat by preventing the heart from beating too slowly. A pacemaker that is connected to a battery with a voltage of 9.0 V and has a capacitor with a capacitance of 110 µF is designed to deliver 5 pulses every 4 seconds. The pacemaker will deliver a pulse to the patients body every time its' capacitor is charged to 0.25 V. What resistance should the pacemaker have to achieve the desired pulse delivery (5 pulse every 4 second). 2-For the circuit below find the current in each resistor using the kirchoff method ww 3.9 1 12 V 1.20 9.8 Ω A ww 6.70 9.0 V B
