Three light bulbs, A, B, and C, have electrical ratings as follows:
Bulb A:  96.0 W, 1.70 A
Bulb B:  80.0 V, 205 W
Bulb C:  120 V, 0.400 A
These three bulbs are connected in a circuit across a 150-V voltage power source, as shown in the figure. Assume that the filament resistances of the light bulbs are constant and independent of operating conditions. What is the equivalent resistance of this combination of bulbs between the terminals of the power source?
