control shed, along with the controller and inverter, became so hot the control shed caught on fire
and burned to the ground. Luckily, the fire burned the insulation off the power wires from the wind
turbine, and they shorted together and shut the wind turbine down before it was destroyed.

PROBLEMS
1. What is the voltage drop across a 100-ohm resistance if the current is 2 amps?
2. How much power is lost as heat through that resistance?
