(1)Consider the circuit in the diagram, with six identical bulbs, three switches, and a battery. For the state with switches 2 and 3 closed, 1 open, rank the bulbs in the order from brightest to dimmest.
(2)Consider the current flowing through bulb 5. All switches are closed, then switch 1 is opened. Does the current through the bulb increase, decrease, or stay the same? All switches are closed, then switch 2 is opened. How does the current through bulb 5 change? Then switch 1 is also opened. How does the current through bulb 5 change? Finally, switch 3 is opened as well. How does the current through bulb 5 change now?
