ELI5: Why does cutting an LED strip or fairy lights still illuminate?

r/

You’re cutting a closed circuit, so then where do the electrons/current go towards to when the strip/wire is cut? How do the individual light units still illuminate?

    The circuit is shaped like a ladder, with the two poles being positive and negative. Each rung of the ladder is a light, with current flowing through it.

    Cut the ladder in half, and you still have a complete circuit.

    the leds are in parallel, the circuit is closed at each LED
