Hi friends, I have a samsung mobile charger with specifications as
Input: 150-300V AC and 0.15A
Output: 4.75V DC and 0.55A
So now by P=VI
the input power is 36W (taking 240V AC and unity PF)
and output power is 2.6W.
So my doubt is why there is such difference the power of i/p and o/p??
because if we have low i/p power we can have a less amount of energy consumed.
