A capacitor of capacitance C = 1 μF has been charged so that the potential difference between its plates is V0 = 295 V. The capacitor is then connected to a resistor of resistance R = 11.5 kΩ. The switch S is closed, and the capacitor begins to discharge. Calculate the time T in s after which the charge on the capacitor has decreased to one fourth its maximum value.
Referring to Figure , draw a graph of potential difference across the resistor versus time, showing at least two intervals of τ . Also draw a graph of currentversus time for this situation.

In the Electric Field Mapping experiment, suppose you used two electrodes separated by a distance L and a power supply with emf Vo Then you measure V for points along a straight line perpendicular to the electrodes, joining the centers of the positive and negative electrodes. You connect the negative terminal of the voltmeter to the cathode and the positive terminal to the pointer placed at a point in the tray along the line joining the two electrodes, a distance d from the cathode. Which of the following is true? O a. The slope of V vs. d is negative. O b. The slope of V vs. d is positive and depends on Vo only. O c. The positive terminal of the voltmeter should be connected to the cathode and the negative terminal to the point between the two electrodes. O d. During the experiment we vary d but keep Va fixed. e. There is a linear relation between d and L.
