# Is this logic correct to determine whether this extension is safe to use with my induction cooktop?

I'm having a hard time understand ampere, power and voltage. I'm not a science student, but want to understand this basic thing.

The max power (I don't know if power is correct to say or not, but max 1200 W is written on it. So I guess this power) of my induction cooktop is 1200 W.

I have a Philips extension which have following written on its back:

6A 250V~ 1500W (Max).

So I assume this means: P = VI So 1500 W = 250V x 6A

It makes sense.

Now, Indian electricity comes at 220 V.

So in that case, my induction cooktop will have the following power relation, when I'm using it at its max power (i.e., 1200 W):

1200 W = 220 V x I I = 1200/220 I = 5.4 approx.

So let's say 5.4 A (ampere) (AM I CORRECT TO CONCLUDE THIS?)

Now, what I've written above is correct, I will assume this basic concept and meanings of voltage, ampere and power are somewhat clear to me.

Now, main question: According to extension specifications, I can use it for a load (is it called load?) of 1500 W. But my load (induction cooktop) is 300 W less, so technically there won't be any problem?

I've seen my friends who use extensions for coolers and they burst/damaged. I don't want that experience.
