Here, V1= 220 V

I₁ = 6A

Time t = 1 day = 24 hrs

Now the electricity consumed will be

= I₁ * V1 * t

= 6 * 220 * 24

= 31680 wh

= 31680 / 1000

= 31.68 kwh

So, electrcity consumed in a day = 31.68 kwh

Again, we have 1 kwh = 3.6 * 10⁶ Joule

So, electricity consumed in 1 day in joule = 31.68 * 3.6 * 10^{6 J}

= 1.14 * 10⁸J
