The electrical voltage is responsible for the light intensity produced
Simple circuit: power supply, control by push-button switch, receiver
When I lower the voltage, electrical and luminous intensities decrease
The speed of the motor and the current it absorbs are also related to the supply voltage
The voltmeter displays 26 V, a pilot inverter 2 ampoules and the ammeter displays 121 mA
The right bulb illuminates much less but the electrical intensity is also much lower
At the same voltage, the ampoules produce a different effect and generate very different intensities as well
It is the receiver that is different (diameter of the filaments)
The physical characteristic is called the resistance of the receiver
The resistance makes it possible to know the intensity as a function of the voltage
It is verified that the polarity here has no influence
For information: the inverter is a flip-flop, to the left: the circuit closes to the right and vice versa
