### Power gain in terms of voltage gain and current gain Formula

power_gain = (Output signal*Output current)/(Input signal*Input current)
Ap = (Vo(t)*i)/(Vi(t)*Ii)

## What does negative power gain dB mean?

If however, the dB power ratio is of a negative value, then this means an attenuation or loss is affecting the circuit as the output power will be less than the circuit's input power. Clearly then 0dB means the power ratio is one with no reduction or gain of the signal
