  2. LED circuit - Wikipedia

    en.wikipedia.org/wiki/LED_circuit

    Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.

  3. Light-emitting diode - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode

    An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .

    In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord.

  7. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component. [1] Consider a very simple circuit consisting of four light bulbs and a 12-volt automotive battery. If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the ...
