Question

An electric heater is rated 1500w . how many energy does it use in 10 hours ?

Answer 1

Energy = Power * Time = 1500 Watts * 10 hours = 1.5 kW * 10 hours = 15 kWh = 15*3.6*10^6 Joules

Answer 2

Hey there!

_______________________________

We are provided with Power = 1500 W

Which when we divide by 1000 we can convert it into KWh

So, 1500/1000 = 1.5KWh

Given Time = 10 hours

We know the formula that

Energy = Power × Time

Energy = 1.5KWh × 10h

Energy = 15KWh

Hence, Total energy consumed in 10 hours by electric heater of 1.5 KWh is 15KWh
