Led Resistor Calculator

Description

We have added a pie chart showing the efficiency of the circuit, the red zone indicates the energy consumption in the resistor, the green zone shows the energy consumed in the led. Really calculate the resistance for your leds in series or parallel, just enter in the fields the source voltage values, the number of leds, led voltage, the led current, touch calculate and you will be able to see the result immediately, If you want to see additional information, touch the + button, then you will see the details of the circuit, such as the pie chart, the calculated resistance, commercial value, colors of the bands, power required, and total consumption of the circuit.
