Question

.An electric geyser of 1500 W is used half an hour a day. What is the energy consumed during this time.

Answer 1

Answer:

0.75

Explanation:

power=1500W(1500/1000=1.5 kWh)                    

time=2 hours                  

∴energy,                                

power=energy/time taken                                

1.5=energy/0.5                                

1.5×0.5= energy                                

0.75 kWh=energy.
