The figure below shows how a bleeder resistor (R = 256 k) is used to discharge a capacitor (C = 80.7 F) after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. Electronic circuit (a) What is the time constant? S www R (b) How long will it take to reduce the voltage on the capacitor to 0.100% of its full value once discharge begins? S (c) If the capacitor is charged to a voltage Vo through a 173 resistance, calculate the time it takes to rise to 0.865V (this is about two time constants). S
