Если сдвинуть влево, то сопротивление уменьшится, и ток в лампах возрастет. Лампы станут светить ярче.
В данной цепи можно найти сопротивление ламп.
R1=U/I1 Где. напряжение и ток берутся из показаний приборов.
Лампы одинаковы, то и их сопротивления одинаковы.
Тогда общий ток через реостат =
I=I1+I2
