A 3-phase delta-connected heater has three heating elements, each with a resistance of 10 ohms. The line voltage is 480V. If one element burns out (opens), what happens to the total heat output?
Answers
AIt drops to 50% of its original output
BIt drops to 66.6% (two-thirds) of its original output
CThe entire heater stops working entirely
DIt drops to 33.3% of its original output
