If 12 series street lights are removed from a circuit, what happens to the voltage on the line?

When 12 series street lights are removed from a circuit, the voltage across the remaining lights will stay the same as long as the source voltage remains constant and the circuit configuration is unchanged. In a series circuit, the total voltage from the power source is divided among the light fixtures based on their resistance.

If lights are removed, the voltage across each remaining light would theoretically increase as the same total voltage is now divided among fewer loads. However, regarding the overall voltage on the line, if the supply voltage remains constant and no other changes are made to the circuit, the voltage present on the line stays the same.

It's also important to note that a circuit is often designed to supply a certain voltage, and removing components may impact the operation of the circuit rather than the voltage supplied by the source itself. This is why the overall voltage on the line is considered to be unchanged in this case.
