A) \[36\times {{10}^{s}}J\]
B) \[34\times {{10}^{s}}J\]
C) \[3\times {{10}^{5}}J\]
D) \[6\times {{10}^{s}}J\]
Correct Answer: A
Solution :
\[1kW={{10}^{3}}\,Wh={{10}^{3}}\,J{{s}^{-1}}\] and \[1h=60\times 60s\] \[1kWh=({{10}^{3}}\,J{{s}^{-1}})\times (60\times 60s)\] or \[1kWh=3.6\times {{10}^{6}}J\]
