So when a lamp has a specification of 24 V, 5.0 W, does it mean that it requires at least 5.0 W to work? Can it still consume more power? Or would it then fail? If for example a power supply has current 8.0 A and potential difference of 24 V, and lamps are connected in parallel, the maximum number of lamps we can insert is 192 W / 5.0 W = 38 lamps. But if we were to have 30 lamps for example, each lamp would receive 6.4 W?
