1. A 577 μF capacitor is discharged through a resistor, whereby its potential difference decreases from its initial value of 81.7 V to 24.1 V in 4.15 s.Find the resistance of the resistor in kilohms. 2. A capacitor of 10.0 μF and a resistor of 120 Ω are quickly connected in series to a battery of 5.00 V. What is the charge Q on the capacitor 0.00200 s after the connection is made? 3. A heart pacemaker fires exactly 6565...
In a heart pacemaker, a pulse is delivered to the heart 81 times per minute. The capacitor that controls this pulsing rate discharges through a resistance of 2.5 x 106. One pulse is delivered every time the fully charged capacitor loses 59.7% of its original charge. What is the capacitance of the capacitor?
QUESTION 19 1 points A capacitor of capacitance Initially neutral, is charged by connecting it in series, to a resistor of resistance Rand a battery of electromotive force e. In which case the time required to charge the capacitor C is longer (the time to have the capacitor charge 99% of its maximum value). E When the resistance R decreases When the resistance R increases. When the electromotive force e increases. When the electromotive force e decreases. QUESTION 20 1...
