Given:-

• cost of electricity is approximately 10 peso per kilowatt-hour

To find:-

how much cost to run a motor for 2 hours if the motor draws 5 ampere in a 220 volt ?

Solution:-

We know that,

• P = VI

Therefore the power consumed is ,

⟹ P = 220 × 5

⟹ P = 1100W

In kilo watt the power would be,

⟹ P = 1100w/1000

⟹ P = 1.1kW

Power consumed in 2 hours is,

= 1.1kW/h × 2h

= 2.2 kW

Therefore cost of running motor for 2 hours is

= 2.2kW × 10 peso/kW

= 22 peso

Final Answer:-

Therefore, 22 peso is the cost of running motor for 2 hours having voltage of 220 and drawing current of 5 ampere
