The figure below shows how a bleeder resistor $$(R=300\mathrm{k}?)$$ is used to discharge a capacitor $$(C=80.0?\mathrm{F})$$ 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? $$\mathrm{s}$$ (b) How long will it take to reduce the voltage on the capacitor to $$0.250\%$$ of its full value once discharge begins? $$\mathrm{s}$$ (c) If the capacitor is charged to a voltage $$V_0$$ through a $$200?$$ resistance, calculate the time it takes to rise to $$0.865V_0$$ (this is about two time constants). s
