Question

An electric iron rated 750Wis operated for 2 hours /day. How much energy is
consumed by the electric iron for 30 dyas?​

Answer 1

Explanation:

Given,

• Iron's capacity : 750Watts
• Operated for : two hrs

We know that,

• 1000 watts/hr = 1 unit/hr
• 750 watts/hr = 0.75 units/hr
• For 2 hrs = 0.75x2 = 1.5 units

Therefore,

• For 30 days = 1.5 units x 30 = 45 units

Hence 45 units are consumed for 30days.

Hope it helps
