[6.] (15 pts) In the figure below, the current flowing thru the 6.25-2 resistor is 1.72 A ww 10.0 + 15.5 ww 6.25 1.72 A ww 12.8 18.2 F 8.50 ww a. What is the voltage of the battery? b. If the 18.2- resistor is increased, will the current provided by the battery increase, decrease, or remain the same? Prove your answer. DO NOT assume the current thru the 6.25 2 is still 1.72 A. HINT for (a.) (i) 1st combine the 12.8-2 and the 18.2-2 in parallel. (ii) Then, combine the 6.25-02 and the 8.50-2 in series. Now you have 2 resistors in parallel. You should then be able to determine how much current flows thru each, and then use this to get the total current in the circuit. For full credit, you must show each of your steps as you break down the circuit.
