| Sep 5, 2015 at 17:41 | comment | added | MaMba | To maximize the power through the load you will need a maximum apparent power, try reducing the value of power-factor. | |

| Sep 5, 2015 at 17:18 | comment | added | MaMba | It makes it louder because resistance is parallel reduces the value of the load resistance hence the overall resistance increases, increasing the current in the circuit. | |
| Sep 5, 2015 at 16:00 | comment | added | soyxan | I have managed to make it a bit louder by placing a 1K resistor in parallel with the load (piezo buzzer). What I am wondering now is why this resistor makes it louder and how to calculate the proper resistor value in order to have the loudest output. | |
| Sep 5, 2015 at 16:00 | comment | added | soyxan | If I mesure the piezo buzzer resistance with a multimeter I get like open circuit. | |
