In the vacuum tube of Figure P34.100, the lower metal plate, the target, is irradiated with \(400-\mathrm{nm}\) light of intensity \(5.50 \mathrm{~W} / \mathrm{m}^{2}\). The frequency of the light is great enough to cause electrons to be ejected from the target and travel to the upper metal plate, the collector. What is the maximum possible current in the circuit if the area of the target is \(600 \mathrm{~mm}^{2}\) ?
