NO, this is property of transformer..amplifiers do amplification at the cost of Battery..so, no need to reduce the other one..zawminoo said:To amplify a thing (eg:voltage or current),we will lost other one thing.
But this is only my suggestion.
soniya_ahuja said:Power can be amplified. This is where the concept of power amplifiers comes into picture.
If you amplify voltage definitely the output power defined by Pout=Vout*Iout will be more than Pin=Vin*Iin. And so you have amplified power.
