"10 units or 10 KWh units" does it use in 4hours.
Step-by-step explanation:
Given,
Power (P) = 2500 W and time (t) = 4 hours
The the commercial unit of energy is Kilowatt hour(KWh).
We know that,
Energy = Power(P) × Time (T)
= 2.5 KW × 4 h
= 10 KWh
= 10 units
Thus, "10 units or 10 KWh units" does it use in 4hours.
