How to connect 500 led bulbs on a 220v AC Quora

If you connect a 1.5 Volt LED to a “1.5” Volt battery, it will initially pass a large current, but the voltage of the battery will drop fairly quickly and the LED will stop shining before the battery is half-empty.

However, you are only lighting the LEDs on one half of the AC cycle, so take another 125 LEDs in series, and connect those in inverse parallel with your first string. So far we now have 250 LEDs running perfectly happily from your 220v AC supply.

Red-tag Joe's introduction to LED lighting and how to

There must be a way to do this without needing a 60v power supply as would be required if you wired the LEDs in series. Well, the answer my friend -- is parallel wiring. When wiring LEDs in parallel you're creating seperate mini circuits, each with their own 6v power supply. Each circuit consists of the battery (positive, ground), an LED and a resistor.

Circuits From Scratch Let’s Put LEDs in Things

If an LED is connect up such that it is emitting light, a multimeter can be used to measure a voltage drop across the LED. This voltage drop usually varies from 1.5V up to 5V, depending on the power output of the LED, and also the color. Low power LEDs tend to have low voltage drops, and high power LEDS have the higher voltage drops. Likewise blue or white LEDs tend have higher voltage drops

How to use Electric Paint with LEDs Bare Conductive

If you would attach an LED to a 5 Volt power supply directly, you would burn it instantly. The high current would destroy the pn-gate. That’s the point where the current limiting resistor comes in. The high current would destroy the pn-gate.

Can I wire a 12v led to a 9v battery? Quora

LEDs are usually considered to be DC devices, operating from a few volts of direct current. In low-power applications with a small number of LEDs, this is a perfectly acceptable approach, for example in mobile phone handsets, where power is supplied by a DC battery.

sir i made this circuit but in presence led still off only in presence of battery they on even after battery remove and supply is on led off. I check voltage at base point when supply is on & battery remove 4.44v & at emitter 4.34 at collector 0.22v and on other hand when battery connect and supply is on at transistor base , emiter & collector
