Question

Find the energy consumed in 10 hours by 5 devices of power 250 W each.​

Answer 1

power consumed by one device=250 watt power consumed by four devices=250x5

= 1250 watt

energy=power x time

energy consumed=1250 x 10

=12500 J

one power :when one joule energy is consumed per hour thin this is called one power or one watt.

Answer 2

$\huge{\fcolorbox{pink}{indigo}{\fcolorbox{lime}{purple}{\fcolorbox{cyan}{black}{\red{Good\: Night}}}}}$

➝ Power by one device = 250 W

➝ Power by 5 device = 250 × 5

➝ Power by 5 device = 1250 W

❥︎ Time taken = 10 hours

$\Large\bf{\color{cyan}We\:know\: that}$

$\orange\star\:\:\bf\purple{Energy\:=\: Power\:\times\:Time\:}$

$\implies\:\:\rm{Energy\:=\:1250\:\times\:10\:}$

$\implies\:\:\rm\blue{Energy\:=\:12500\:J\:}$
