Question

an electric bulb of 100 watts is used for 3 days. Calculate the electrical energy consumed per day.​

Answer 1

e= p*t

p=100

t=3*3600

t=10800sec

e=100*10800

e=1080000 j

Answer 2

The electrical energy consumed per day:

• Given that an electric bulb of 100 watts is used for 3 days

• Electrical energy is the power consumed by the appliances in one hour

• Electrical energy = Power × Time

• Energy is given in kilowatt per hour or watt per sec or watt per hour

• Energy per day = 100 watt × 24 hr

= 2400 watt hr
