Answer:
Power will be 166.66 watt when the heater are connected in series
Explanation:
We have given power of the first heater = 490 watt
And power of the second heater = 250 watt
We know that in series connection potential difference will be same
So let the potential difference is v
Power is given by
So
Similarly
As resistances are connected in series so equivalent resistance
So power
