10. [-14 Points] DETAILS MY NOTES ASK YOUR TEACHER Four resistors are connected to a battery with a terminal voltage of 12 V, as shown in the figure below. Use the following variables as necessary: R1 = 27.00 and R2 = 86.02. 50.00 w w w 20.00 12V (a) How would you reduce the circuit to an equivalent single resistor connected to the battery? Use this procedure to find the equivalent resistance of the circuit. (b) Find the current delivered by the battery to this equivalent resistance. A (c) Determine the power delivered by the battery. w (d) Determine the power delivered to the 50.0 A resistor. w 11. [-12 Points] DETAILS MY NOTES ASK YOUR TEACHER Two 1.80 V batteries--with their positive terminals in the same direction--are inserted in series into the barrel of a flashlight. One battery has an internal resistance of 0.3402, the other an internal resistance of 0.160 2. When the switch is closed, a current of 0.600 A passes through the lamp. (a) What is the lamp's resistance? 12 (b) What fraction of the power dissipated is dissipated in the batteries? %
