If a TV of rating 100 W operates for 6 hours per day, find the number of units consumed in a leap year.

Explanation

Data : P=100 W, t=`6("hours")/("day")xx366 ` days =2196 hours
1 unit `-= 1 kW *h=1000 W*h`
`N=(Pt)/(1000 W*h//"unit")=(100Wxx2196"hours")/(1000 W*h//"unit")`
219.6 units be consumed in a leap year.
