Hi Aashi,

I guarantee that ur concept will be clear by the end of my answer. Try to solve the question together

This is regarding the flow of charge aka current

Like any problem in physics this can also be solved using multiple ways.

That’s the beauty of physics :)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here the manufacturer has not provided the resistance of the product

but we can easily find it with the given power and voltage

R = V2/P = 22 ohms

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now v r connecting it to a circuit

I = V/R = 220/22 = 10A

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Energy = Pt = (220W) x (3x60x60 secs) = 23760 KJ

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Hope u enjoyed physics :)
