Question

Family used 250 unit of electrical energy during a month calculate this electrical energy in joules

Answer 1

$\huge\star\sf\underline\pink{Solution:-}$

We know that,

250 units of Electrical Energy = 250 KWh

$\\ \sf{ 1\:kWh \:of\: Energy = 3.6 \times 10^6 \:J} \\ \\ \sf{so,} \\ \\ \sf{ 250\:kWh\:of\: Energy = 3.6 \times 10^6 \times 250 \:J } \\ \\ \\ \longrightarrow\sf{9 \times 10^8 \:J}$

Thus,

250 Units is Equal to $\sf\orange{9 × 10^8}$ joules.

Additional Information:

• 1 kilowatt-hour of electrical energy is commonly known as '1 unit' of electricity.
