Why Use 220 Ohm Resistor at Kimberly Hawthorne blog

Why Use 220 Ohm Resistor. the easy answer is that a 200 ohm resistor is a common resistor included in many experiment kits. all leds on any circuit require a current limiting resistor to limit the current to typical 20 ma level which is why we picked 220 ohm for a 5. Current circuit voltage is 5, resistor is 220 ohms. We want to use a common resistor if. what i have thought: ohm's law, at least on paper, seems to indicate a resistor in the ballpark quite a bit lower than the 220 ω i see on. Stay on the cutting edge:. a 220 ohm resistor with a 5% tolerance will be between 209 and 231 ohms. 5% might not be considered that accurate these days (but still. For basic tasks, the exact value isn’t essential but when designing. So i = u/r = 5v/220ohm = 0.0227a = 22.7ma. in the standard series of resistors we can use this exact value or we can choose a 150 or 220 ohm resistor instead. let’s use a 220 ohm resistor, which is commonly used with led lights, as an example of how to read resistor color codes.
