WebIf we use the 110v standard of the US, we first calculate the peak voltage, 1.4 * 110 = 156 and we can find the number of LEDs it can support: 156 / 3.3 = 47 LEDs So, does that mean that if we put 47 LEDs in series, we can run the whole string directly off a 110v AC socket? The answer is Yes! WebWhere a series circuit receives the same current to each LED, a parallel circuit receives the same voltage to each LED and the total current to each LED is the total current output of the driver divided by the number of parallel LEDs. Again, don’t worry, here we will see how to wire a parallel LED circuit and that should help tie the ideas ... WebApr 6, 2024 · Watts are the amount of energy a light bulb uses.
