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

a) We assume that the switch is on. Calculate the reactance values and find the charging current in the circuit below. Is the circuit capacitive or inductive? Show that the voltage across the capacitance can be slightly larger than the source voltage U. (This is called the Ferranti effect and means that we can get a voltage rise beyond overhead lines with small loads. This is mostly relevant at the highest voltage levels. The frequency f is 50Hz, and assume voltage U= √2⋅24kV
