Problem 31.9: Find power with R from V and I graphs

Please wait for the animation to completely load.

Assume an ideal power supply. The voltage of the source as a function of time is the red plot on the graph, and the current from the source is black (voltage is given in volts, current is given in milliamperes [mA = 10-3 A], and time is given in seconds). Restart. What is the power dissipated in each circuit?

  1. Circuit I: RC Circuit
  2. Circuit II: RL Circuit
  3. Circuit III: RLC Circuit
