The figure below shows how a bleeder resistor (R = 270 k?) is used to discharge a capacitor (C = 80.0 µF) after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. Electronic circuit R C (a) What is the time constant? 2.16E-5 s (b) How long will it take to reduce the voltage on the capacitor to 0.350% of its full value once discharge begins? -1.22E-4 s (c) If the capacitor is charged to a voltage $V_0$ through a 225 ? resistance, calculate the time it takes to rise to 0.865$V_0$ (this is about two time constants).

a. What is the potential difference across each resistor in Figure $\mathrm{P} 23.6 ?$ b. Draw a graph of the potential as a function of the distance traveled through the circuit, traveling clock-wise from $V=0 \mathrm{V}$ at the lower left corner. See Figure $\mathrm{P} 23.9$ for an example of such a graph.
