2 generators are connected to the bus below.

Given
V1 = 300V, 50Hz
V2 = 400V, 60Hz
When the switch is opened, calculate
i) the maximum and minimum voltage across both light 1 and 2.
ii) peak voltage across both lights
iii) maximum number of light pulsation

How do I solve the issue above? Any guidelines? Where do I start?
