Before working with these circuits, you are asked to make some predictions: (a) What is the brightness of the bulbs in circuit II relative to each other and to the bulb in circuit I? (b) If one of the bulbs is removed in circuit II, how will the brightness of the other bulb be affected? Does it matter which bulb is removed?
