Calculate the number of units consumed by a TV in a leap year which is rated at 100 W if it is used 6 hours per day.

Text Solution

Verified by Experts

Data : P = 100 W, ` t = 6 (" hours")/("day") xx 366 "days" ` = 2196 hours
1 unit = 1 kW.h = 1000 W.h
N = ` (Pt)/( 1000 W.h.//"unit") = ( 100 W xx 2196 " hours")/(1000 " W.h/ unit")= 219.6 " units"`
219.6 units are consumed in a leap year.
