WebOct 28, 2024 · If your LED takes 100 mA at 3.3 volts (for instance) you would need to drop 1.7 volts from 5 volts with a resistor. That means a resistor of value 1.7 volts / 100 mA = 17 ohm. Now, if your 5 volt rose to 5.1 volts, the 100 mA would rise to no more than 1.8 volts / 17 ohm = 106 mA. WebIF the bulbs have the same wattage rating, then the 12V bulb will have the highest resistance. So, assuming the wattage rating of each bulb is W watts, then W= V*I, and I = W/V and R =V/I = V^2/W. So, a 12 V bulb will … WebAnswer (1 of 7): Yes and no. As with all electrically conductive materials, LEDs develop a voltage drop across them when you draw current through them.

"WebResistance is measured in ohms, often written as the symbol Ω. The bigger the resistance value (in ohms) the more it fights. Most resistors you'll see range between 1 ohm and 1 megaohm (1.0 MΩ). Since the resistive element is inside a ceramic casing, its not possible to tell the resistance of a resistor just by looking at it. " - Green led resistance
