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.
