Question

Two identical heaters, each marked 1000 watt, 250 volt are placed in parallel with each other and connected to a 250 volt supply. The net rate of heat will be (combine by both):

• A. 250W
• B. 500W
• C. 1000W
• D. 2000W

Answer 1

The correct option is D 2000W

As they are connected in parallel , both of them will work independently also due to parallel connection both will get equal voltage. Therefore net power consumption will be sum of both the heaters. because the applied voltage is equal to rated voltage so power power consumption will be equal to rated power by both bulbs.

Hence $P_{net}=1000W+1000W$$\therefore P_{net}=2000W$
