Document Summary
No work needs to be shown and no partial credit. will he given. (6 pt. s) 1. The electrical power consumed in resistor r1 is 9 xv. If r3 = r1 /3. then the electrical power dissipated in resistor r3 is (a) zero (b) 1 w (c) 3 w (d) 9 w (e) 27 xv (f) 36 xv. The two resistors have equal values of resistance. When the switch is closed, the current i through the battery. (a) stays the same (h) (lecreases (c) increases (6 pts) 3. Recall that for a capacitor, c = q/v. At time t after the switch is closed, the current in the resistor is 2. 0 a. At that instant the charge on the capacitor is. 4. ,s. j (a) zero (b) 4. 8 x 10 c (c) 9. 6 x i0 c (d) 1. 44 x 10 c (e) none of the above answers.
