Question

find energy 1 kwh consumed in 10 hours four devices of power 500 w h​

Answer 1

Answer:

energy consumed in 10 h by four devices = 4×500 ×10/1000

= 20000/1000

= 20 kwh or units

Answer 2

Answer: 50J

Explanation:

Power = 500w

1w=1/1000kwh

500/1000 = 0.5kwh

Time = 10 h

E=PxT

E=0.5x10

E=50j
