José Calculating an LED resistor value An LED must have a resistor connected in series to limit the current through the LED, otherwise it will burn out almost instantly. The resistor value, R is given by: R = (VS - VL) ÷ I R = resistor value in ohms (ohm). VS = supply voltage. VL = LED voltage (2V, or 4V for blue and white LEDs). I = LED current in amps (A) LED resistor circuit The LED current must be less than the maximum permitted for your LED. For standard 5mm diameter LEDs the maximum current is usually 20mA, so 10mA or 15mA are suitable values for many circuits. The current must be in amps (A) for the calculation, to convert from mA to A divide the current in mA by 1000. If the calculated value is not available choose the nearest standard resistor value which is greater, so that the current will be a little less than you chose. In fact you may wish to choose a greater resistor value to reduce the current (to increase battery life for example) but this will make the LED less bright. For example If the supply voltage VS = 9V, and you have a red LED (VL = 2V), requiring a current I = 20mA = 0.020A, R = (9V - 2V) ÷ 0.02A = 350ohm, so choose 390ohm (the nearest standard value which is greater). LED voltage The LED voltage VL is determined by the colour of the LED. Red LEDs have the lowest voltage, yellow and green are a little higher. Blue and white LEDs have the highest voltages. For most purposes the exact value is not critical and you can use 2V for red, yellow and gr

Q: What voltage for the Lithium battery. How many cells?
尋ねた iflyj3 に 2020-09-12 02:41:22
José I haven't received my Spot Welder Machine yet but when it arrive I'm thinking about using my bench power supply at 12v 7a, but maybe you can use a 18650 4-cell battery pack

Q: Input 12v 30 amp Output 72v ** amp How much current can it supply outpu at 72v plz answer me
尋ねた BG483244534 に 2020-09-03 06:42:39
José Right now with little time to think, so you have an input of 12v 30a 360w, 12 × 30 = 360, 360 ÷ 72 = 5a, but I don't know if it's right because I did the math very quickly just to be able to answer.
