- | You need to be able to deliver different amounts of power to the generator; however, you are not sure that the 100 V primary power supply in the particle generator will be sufficient to power these systems. You manage to find some additional batteries (three 10 V batteries from the supply room) to use if you need them. | + | You need to be able to deliver different amounts of power to the hawkion |
