NEET Physics Power Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Power unit (i) 1 J s –1 (b) Horse-power (ii) 1000 W (c) Watt in kWh (iii) 746 W (d) Energy usage (iv) 3.6 × 10 6 J
Choose the correct matching:
a-i, b-iii, c-ii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-ii, c-i, d-iv
a-iv, b-i, c-iii, d-ii
Correct Answer
Detailed Explanation
The unit of power is correctly defined as 1 J s –1 (watt), while horse-power is 746 W. A 100 watt bulb used for 10 hours consumes energy equivalent to 1 kilowatt hour (kWh), which is 3.6 × 10 6 J.
