A 1.5-F capacitor in a television set is charged by a 22,000-V potential difference. To prevent harm to the television repair technician, a large “bleeder” resistor is connected across the capacitor’s ends. When the television set is turned off, the capacitor discharges through the bleeder resistor rather than through the technician, who might accidentally touch its ends. (a) Calculate the time needed to discharge 95 percent of the charge on the capacitor through a 1.0 MΩ resistor. (b) What is the total charge that must be discharged

Question
A 1.5-F capacitor in a television set is charged by a 22,000-V potential difference. To prevent
harm to the television repair technician, a large “bleeder” resistor is connected across the
capacitor’s ends. When the television set is turned off, the capacitor discharges through the bleeder
resistor rather than through the technician, who might accidentally touch its ends. (a) Calculate the
time needed to discharge 95 percent of the charge on the capacitor through a 1.0 MΩ resistor. (b)
What is the total charge that must be discharged?
