You set up the circuit shown in Fig. 26.20, where C = 5.00 Ã— 10^-6F. At time t = 0, you close the switch and then measure the charge q on the capacitor as a function of the current i in the resistor. Your results are given in the table:

(a) Graph q as a function of i. Explain why the data points, when plotted this way, fall close to a straight line. Find the slope and y-intercept of the straight line that gives the best fit to the data.

(b) Use your results from part (a) to calculate the resistance R of the resistor and the emf E of the battery.

(d) When the voltage across the capacitor is 4.00 V, what is the voltage across the resistor?

i (mA) 4 (C) 48.0 40.0 30.2 32.0 40.0 24.0 49.9 56.0 10.1 19.8
