Answer:
500 watts
Step-by-step explanation:
500 W
In these types of questions it is always better to find the resistance of the equipment (heater element).
R=V2/P:whereV=250V,P=1kWR=V2/P:whereV=250V,P=1kW
This gives resistance of each heater element to be 62.5ohm.62.5ohm.
Therefore combined resistance of the heater element in series= 125ohm.125ohm.
Now you can either calculate the series current I=V/R=2AI=V/R=2Aand find the power drawn from the supply as P=I2∗RP=I2∗R
or
Directly calculate the power drawn by using P=V2/R.P=V2/R.
Both ways you will get the answer as 500W.
