A current limiting resistor and a variable resistor in a laser diode circuit diagram Most electronic components have a limit on the maximum current they can handle. If you exceed this current limit, the parts will not work and might burn out.
Current-limiting resistors are widely used in electronics to regulate current levels, ensuring that devices operate safely within their specified limits. By using this calculator, users can quickly determine the right resistor value based on supply voltage, component voltage drop, and the maximum allowable current.
Now you know you need a 150-ohm resistor to limit the current to 20mA. The resistor “takes the hit” by dropping voltage and resisting the flow of excess current. It’s placed in series, meaning the current must pass through it before reaching the component. That’s how it controls the flow.
Yes, using a slightly higher resistor value will reduce the current further, which can increase component lifespan. However, using a significantly higher resistance may cause insufficient current, affecting circuit performance.
