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 Rtorso, allowing the heart's normal rhythm to be reestablished. (a)If the capacitor is initially uncharged with C = 8.25 µF and  = 1270 V, find the value of R (in ohms) required to charge the capacitor to a voltage of 755 V in 1.70 s. answer in  Ω b) If the capacitor is then discharged across the patient's torso with Rtorso = 1260 Ω, calculate the voltage (in V) across the capacitor after 4.50 ms. answer in V

Please answer carefully.

The figure below shows how a bleeder resistor (R = 246 kΩ) is used to discharge a capacitor (C = 77.7 µF) 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? (in s)(b) How long will it take to reduce the voltage on the capacitor to 0.100% of its full value once discharge begins? (in s)(c) If the capacitor is charged to a voltage V0 through a 123 Ω resistance, calculate the time it takes to rise to 0.865V0 (this is about two time constants).(in s)

A circuit consists of a resistor R1 = 126 Ω, a resistor R2 = 275 Ω, a capacitor C = 182 mF, a switch, and an e = 3.00-Vbattery, all connected in series. Initially the capacitor is uncharged and the switch is open. At time t = 0 the switch isclosed. (a) What charge will the capacitor have a long time after the switch is closed? (b) At what time will the chargeon the capacitor be 80.0% of the value found in part (a)?
