STATEMENT The circuit with three identical incandescent lamps, represented in the figure, consists of a mixed association of resistors. Each lamp L₁, L₂ and L₃ is connected, in parallel, to a resistor of resistance R, forming a set. These sets are connected in series, with all lamps having the same brightness when connected to the power source. After several days of use, only lamp L₂ burns out, while the others remain lit. Regarding the situation where all lamps are working, after L₂ burns out, the brightness of the lamps will be: A) the same. B) more intense. C) less intense. D) less intense for L₁ and the same for L₃. E) more intense for L₁ and less intense for L₃.
