Islands game:

Complete Circuit: No need

Electric current: Flows from the energy source to the last circuit component, amount of current is fixed

Voltage: Coal generator is 10V, solar panel is 20V, all bulbs use 1V and some other components use 2V, all numbers are fixed. When it has gone to the last component, there is still voltage left there and it is not used. If the voltage is not enough, the other bulbs will get ignored

Resistance: There is no specific resistance value, it is all equal to the voltage use there.

You cannot use parallel circuits without the splitter.

Real science:

Complete circuit is required

Electric current flows from the positive terminal of the cell to components and to the negative terminal of the cell

Voltage: All voltages are used up when it got back in the negative terminal of the cell. Voltage used by components are based on resistance

Resistance: Different components have different resistance. The ohm's law is V=IR

You can make series and parallel circuits like how you want to do it.
