To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum ...

Not only can one select a target current to put through an LED, but by providing a target voltage, the system will automatically calculate the necessary series resistor. If for example the LED is ...

When resistors are connected in series, the current through each resistor is the same ... potential difference across them. In order to calculate the total resistance of two resistors connected ...
