Question

An electric bulb of 60w is used for 6 h per day.calculate the unit of energy consumed in one day by the bulb.

Answer 1

Watt is joule per second
so

60*6*60*60=1296000 joules

Answer 2

$\huge\underline\mathfrak\green{0.36Kwh \: or \: 0.36 unit}$

Step-by-step explanation:

We know that.

Energy = Power x Time.

1Kw = 1000 watt

So, 60 watt = 60/1000 = 0.06

So,

$\bf\huge ENERGY = 0.06 \times 6 \\ \\ \bf\huge = > 0.36kwh$

$\huge\fbox\red{ 0.36Kwh or 0.36Unit}$
