Functions of Resistor Contd. (LED Current Limit)

Just like in transistor biasing as discussed yesterday LEDs(Light Emitting Diodes) too are very sensitive to high currents. A resistor when placed in series with the LEDs regulates a proper flow of current through them. To calculate the value of a series LED resistor, the following formula may be used: R = V –( N.V … Continue reading Functions of Resistor Contd. (LED Current Limit)
