Question

an electric iron consumes 1000 watt of power find the energy consumed by it for 10 hour​

Answer 1

Correct option is

Correct option isC

Correct option isC10 kWh

Correct option isC10 kWhGiven : P=1000 W =1 kW t=10 h

Correct option isC10 kWhGiven : P=1000 W =1 kW t=10 h∴ Energy consumed in 10 h E=Pt=1×10=10 kWh

Answer 2

Here it is given that,

An electric iron has

Power = $1000$ watt

Time = $10$ hour

As we have to find the energy which is consumed by the $10$ hour,

By converting the watt into kilowatt,

$=>1000$ watt = 1 kilowatt       ....(divide the value of power by 1000)

We have the formula,

Energy = Power × Time

The energy which is consumed by the $10$ hour,

$=>1$ kw × $10$

$=>10$ kWh

Hence, the energy which is consumed by the $10$ hour is $10$ kWh.
