Question

A certain household has consumed 260unit if energy during a month how much energy is consumed in Jules

Answer 1

1 unit =1 kWh
1kWh=3.6 x10^6 j
260 units=260x 3.6 x10^6 j =936 x10 ^6 joules

Answer 2

Given :

The energy consumed by the house in a month = 260 units = 260 kWh.

We know that 1 kWh = 3.6 × 10^8 J

So the energy consumed by the house in joules =

= 260 × 3.6 × 10^8

=936 × 10^8 joules.

= 9.36 × 10^10 joules.

Definition of 1 kWh :

Energy consumed in 1 kWh if a machine or appliance of 1 kilowatt power is operated for a period of 1 hour.
