Question

Number of KWh in 1 Joule.

• A. $3.6\times {10}^{6}KWh$
• B. $2.77\times {10}^{-7}KWh$
• C. $600KWh$
• D. $1.6\times {10}^{-19}KWh$

Answer 1

The correct option is B $2.77\times {10}^{-7}KWh$

We know that $KWh$ is kilo watt-hour-

In SI unit-

$K={10}^3$

$hour=3600s$

$1kWh=3.6\times {10}^{6}J$

$\therefore$ $1$ $J=\frac{1}{3.6\times {10}^6}=2.77\times {10}^{-7}$ $kWh$
