question_answer
Two identical heaters rated 220 volt, 1000 watt are placed in series with each other across 220 volt lines. If resistance do not change with temperature, then the combined power is
A) 1000 watt
B) 2000 watt
C) 500 watt
D) 4000 watt
Correct Answer:
C
Solution :
Power of the combination \[{{P}_{s}}=\frac{P}{n}=\frac{1000}{2}=500\,W\]
