Question

An electric heater is rated 1500 watt. How much energy does it use in 10 hours. Find the unit also

Answer 1

Answer:

Power=energy /time

power=1500w

time =10×3600=36000

energy =power ×time

=1500×36000

54000000=54×10^6

Answer 2

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$

P = 1500 W

★Change it in kwh

= 1.5kwh

t = 10 hour

Energy = Power × Time

= 1.5 × 10h

= 15kwh

= 15 units

★Consumed energy = 15 units
