Answer 2

Answer:

Given:

for 250 watt bulb

P=250 watt

t=5hours

for 6 watt bulb

P=6watt

t=4.5hours

Explanation:

formula:

Energy=power×time

for 250 watt bulb

E=250×5

E=1250 Wh

E=1.25 kWh

for 6 watt bulb

E=6×4.5

E=27 Wh

E=0.027 kWh

Total Energy...

E = E of 250 +E of 6 watt

E = 1.25 + 0.027

E = 1.277 kWh
