in KWh.​

Answer 1

Answer :-

Given :-

• Power of electric iron = 1200 W = 1.2 Kw

• Time = 90 mins = 1.5 hrs

To Find :-

• Electrical energy ( in kWh )

Solution :-

Electrical energy = Power × Time

Substituting the value in formula -

⇒ E = P × T

⇒ E = 1.2 × 1.5

⇒ E = 1.8

Electrical energy = 1.8 kWh
