Part a
the voltage (in V) across the 200 W , 120 V bulb is
80.
the voltage (in V) across the 100 W , 120 V bulb is
160.
Part b
the power dissipated (in W) by the 200 W , 120 V bulb is
88.888889
the power dissipated (in W) by the 100 W , 120 V bulb is
177.77778
Part c
the 200 W bulb will be approximately half as bright as normal , the 10 W bulb would be much brighter (almost twice as bright) than normal and would probably burn o
ut in few minutes
