PARALLEL CIRCUIT WITH THREE LIGHTBULBS
While the pushbutton P is pressed, the voltage of the batteries reaches the three lightbulbs, turning on lightbulb L1 with a higher intensity with respect to L2 and L3, which are less bright, due to double the current intensity reaching L1 than L2 and L3. If L1 fuses (unscrew), L2 and L3 also turn off. If L2 or L3 fuse, the other lightbulbs keep shining. Why?
