When U r making a video on international level please make sure U do some practice and have a command on language and knowledge of each component properly
droop mode, a generator's output and frequency are inversely proportional. When frequency decreases, output increases. If a generator has a 5% droop setting, for example, then a 5% decrease in frequency will increase the unit's power output by 100%.In layman terms voltage gain can be defined that how much the output voltage is greater than the input voltage for an amplifier. Technically it is the ratio of the OUTPUT VOLTAGE to the INPUT VOLTAGE
