Answer 1

HEY MATE HERE IS YOUR ANSWER

HOPE IT'S HELPFUL

FORMULA USED IN THE SUM

ENERGY = POWER INTO TIME

OR POWER X TIME

Answer 2

Given:

Electric bulb power consumption $=100$ $W$

Electric iron power consumption $=750$ $W$

Television power consumption $=100$ $W$

Time $=3$ $hour$

To find:

Energy consumed per day.

Solution:

We have been given the total power consumed by different appliances in a day and each appliance is used for a total of 3 hours.

The energy consumed by the appliances is given by the power consumed multiplied by the time of running.

$E=P$ × $t$

Now,

The total power consumption,

$P_{total} =P_{1} +P_{2} +P_{3}$

$P_{total} =100+750+100$

$P_{total} =950$ $W$

$P_{total} =0.950$ $KW$

Hence, the total energy consumption will be

$E_{total}=P_{total}$ × $t$

$E_{total}=0.950$ × $3$

$E_{total}=2.85$ $Kwh$

Final answer:

Hence, the total energy consumption of the house will be 2.85 kilo watt hour per day.
