Consider this circuit. In case there is a problem, here is the description: resistor B and a switch are in parallel, and this parallel combination is connected in series with a battery and with resistor A. The switch is now open. When the switch is closed, please describe what happens to each of the three quantities and why. The choices are increase, decrease, or stay the same, but be sure also to explain why each happens.

a) current through A

b) current through B

c) total power output by the battery
