Question

Energy spent in kilowatt-hour $=\frac{volt\times ...........\times ......}{1000}$.

• A. ampere, hour
• B. ohm,min
• C. ampere,min
• D. joule,hour

Answer 1

Answer: (A)

Energy = Work done $\left(inWatt\right)=Power\times time=Voltage\times current\times time$

$Workdone\left(inkilowatt\right)=\frac{(Voltage\times current\times time)}{1000}$

$Orworkdone\left(inkilowatt\right)=\frac{(Volt\times ampere\times hour)}{1000}$
