WebA circuit is a complete path around which electricity can flow. It must include a source of electricity, such as a battery. Materials that allow electric current to pass through them easily, called conductors, can be used to link the positive and negative ends of a battery, creating a circuit. WebDec 4, 2015 · The mechanics of the bulb and its electronics are dead simple. The two-sided circuit board seems to have been reflow soldered. Two wires connect the board to a metal plate holding 30 LEDs. Two more wires go to the light socket conductors. All four of these wires look as though they were hand-soldered.
