Astrand of 10 lights is plugged into an outlet. how can you determine if the lights are connected in series or parallel?
a) unscrew one light. if the other lights stay on, it's a series circuit.

c) unscrew one light. if the other lights turn off, it's a series circuit.
d) cut the strand in half. if the plugged in half stays on, it's a series circuit.

Series circuits, the current runs through all of them and they are conncted by the bulbs, so if you unscrew one, all light turn off

paralell, they are kinda independent, if you unscrew one, nothing happens to others
