An electric heater is rated 1500 W. How much energy does it use in 10 hours?

Answer:

With the help of the expression, energy consumed by an electric heater will be

obtained,

P = T

Where,

The power rating of the heater,

P = 500 W = 1.5 power unit Time that the heater has operated,

T = ten h Work done = Energy consumed by the heater

Therefore, energy consumed = Power × Time

= 1.5 × 10 = 15 kWh

**Hence, the energy consumed by the heater in 10h is 15 kWh.**

"hello students welcome to leader
learning
this is ashwini i teach science at
leader so here
we have a question that is an electric
heater is rated 1500 watt
we have the power it is in what so
1500 what how much energy does it use
in 10 hours we have to find the energy
usage
okay with the help of the expression
energy consumed by an electric heater
will be obtained
where the power rating of the heater is
p equals to 1500 watt
so here we can convert it 1500
divided by 1000 okay
so we got the value it is 1.5
power
per unit time okay it is per unit
time so
we got it as 1.5 power per unit time
now time is basically we have to find it
for 10 hours so we can write it as
10 hours
here work done equals to energy consumed
by the
heater okay it is basically the energy
consumed by the heater
therefore energy consumed equals to
power into time so we got the values we
just put the values in this equation
we have power is 1.5 multiplied by
time is 10 so here we got our answer
it is 15 right so hence the energy
consumed by the heater in 10r
is 15
here is the answer that the energy
consumed by the heater is
10 in 10 r is 15 kilowatt per hour
if you have any doubts then please put
it down in the comment section
for more such video solutions please
