I have a series circuit with a 1000 ohm resistor, a 3mm LED red bulb and a 6200 ohm resistor in series. The input voltage is 5.02 volts and the input current is 0.46 mA. Using this info, I have calculated the LED resistance to be 3713 ohms. Is it possible that the LED has such a high resistance?

NettetIn a series resistor network the individual resistors add together to give an equivalent resistance, ( RT ) of the series combination. The resistors in a series circuit can be … NettetSeries resistor is a circuit when we connect multiple resistors in a single wire. We connect the end of the first resistor to the head of the second resistor and so on. Series resistor connection has the same value of current. The voltage drop across each resistor is proportional to the sum of the resistances and follows Ohm’s law (V = I x R). tail golf shorts for ladies https://ptforthemind.com

NettetRunning a series circuit helps to provide the same amount of current to each LED. This means each LED in the circuit will be the same brightness and will not allow a single LED to hog more current than another. When each LED is receiving the same current it helps eliminate issues like thermal runaway. twilight galaxy glockNettetJust use the standard resistor values chart to find the nearest highest value available. Example 1: The blue LED has a typical forward voltage drop of 3.2 V, therefore a 5 Ω resistor is required when using a 3.3 V supply voltage. However, if you are using a 5 V supply voltage, then a 90 Ω resistor is needed. As you can see, the resistor ... twilight galaxyNettetDigiKey's LED series resistor calculator uses supply voltage, forward voltage, and forward current values to help you identify the correct series resistor.
