Single phase, 230 V, 1 KW heater is connected acrose single phase 230 V, 50 Hz supply through a diode. The power delivered to the heater element:

  1. 500 W
  2. 100 W
  3. 1000 W
  4. None of the above

Correct answer: 1. 500 W

Explanation:

Given that Resistance of heater R = 2302/1000 = 52.9 Ω

Now, Vm = 230√2

Vor = Vor2/R = 500 W.
