Quantitative Problems (SHOW YOUR WORK FOR PARTIAL CREDITS 11-1) 110pts) For the circuit shown in the figure, V-20 V, C- 10 uF, R-0.80 M2 and the battery is ideal. Initially the switch S is open and the capacitor is uncharged. The switch is then closed at timer-0.00 s. What is the potential difference across the resistor 20 s after closing the switch? (Remember V-VR+Ve because R and C are in series) 11-2) I 12pts] Three resistors with resistances of 2.0 60 n, and 12 are connected across an ideal de voltage source V, as shown in the figure. If the total current in the circuit is I- 5.0A, what is the current through the 12-12 resistor? 2.0 6.0 12

Explanation / Answer

Total current through the circuit = 5 A

Current through 12 ohm = IR2R3 / (R1R2+R2R3+R3R1)

= 5*2*6 / (12*6+2*6+12*2)

= 0.55 A
