Question 33

A geothermal exploration probe uses two different resistive heating systems to maintain its internal temperature:

  • System 1: A steady direct current III is passed through a heating element of resistance RRR, dissipating a power PPP.
  • System 2: An alternating current with a peak value of 3I3I3I is passed through a secondary heating element of resistance 0.4R0.4R0.4R.

What is the average power dissipated by the secondary heating element in System 2?
