The figure below shows how a bleeder resistor (R = 159.9 kΩ) is used to discharge a capacitor (C = 73.3 µF) after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. How long will it take to reduce the voltage on the capacitor to 0.100% of its full value once discharge begins?
Figure 20.47 shows how a bleeder resistor (R = 260 kohm) is used to discharge a capacitor (c = 70.mu F) after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. (a) What is the time constant? s (b) How long will it take to reduce the voltage on the capacitor to o.300% of its full value once discharge begins? s (c) If the capacitor is charged to a voltage...
A device with resistance of 2.5k 2 is used to discharge a capacitor with capacitance of 8m F after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. How long will it take to reduce the voltage on the capacitor to 0.350% of its full value once discharge begins? (s) 0 145 1.13 O 0.145 O 0.113 113
The figure below shows a simplified model of a cardiac defibrillator, a device used to resuscitate patients in ventricular fibrillation. R с Ž Rorso When the switch S is toggled to the left, the capacitor C charges through the resistor R. When the switch is toggled to the right, the capacitor discharges current through the patient's torso, modeled as the resistor Reorso, allowing the heart's normal rhythm to be reestablished. HINT (a) If the capacitor is initially uncharged with C...
