Problem 31.1: Power of light bulbs (with switches)

Open/Close Switch #:

Please wait for the animation to completely load.

Assume an ideal power supply. The graph shows the voltage across the power supply (red) and current (x 100) from the power supply (blue) as a function of time (voltage is given in volts, current is given in hundredths of amperes, and time is given in seconds). A measurement of a current of 50 on the graph would actually be a current of 0.5 A. Find the power rating of each of the bulbs A, B, C, and D. Restart.
