NEET Physics Power Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Unit of Power (i) 1 J s –1 (b) Horse-power (ii) 3.6 × 10 6 J (c) 100 watt bulb (iii) 746 W (d) Kilowatt hour (iv) 1000 watt hour
Choose the correct matching:
a-i, b-iii, c-ii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
The unit of power is defined as 1 J s –1 (watt), the horse-power is equivalent to 746 W, a 100 watt bulb uses energy equal to 1 kilowatt hour after being on for 10 hours, and 1 kilowatt hour equals 1000 watt hours.
